• Isopropyl okay to use on MacBook screen?

  - by Archagon

  I've always used a mixture of isopropyl alcohol and distilled water to clean my computer screens (50% water and 50% * 70% isopropyl). From what I understand, these are exactly the same ingredients used in most commercial screen cleaners, perhaps even more diluted. I recently used this solution to wipe off my 2010 MacBook Pro screen, and there don't seem to be any problems, but this support page explicitly says not to use isopropyl. Now I'm worried that I might have inadvertently damaged something. I'm also concerned because I once managed to dissolve the surface rubber lining of one of my mice with the isopropyl solution, and the MacBook Pro display has a thin rubber bezel keeping the glass in place. Why would Apple single out isopropyl on their support page? Should I be concerned?

• Connect Lenovo Thinkpad Edge e120 to WQHD display (such as Dell U2711) through HDMI

  - by Fulvio

  On paper, the HDMI version of the Lenovo Thinkpad Edge e120 is 1.3, which supports WQHD. Does it actually work? I want to connect the e120 to a WQHD display, such as the Dell U2711 or an Apple Cinema Display. I run Windows 7 Ultimate and latest drivers. The e120 I think has the Intel HD Graphics 3000 onboard chipset. I don't have the chance to test out the e120 with neither of these displays, so I'm seeking for an opinion from those who have tried. Thank you

• Macbook Pro (SantaRosa) internal display not detected by graphics card, external monitor OK

  - by BLAU

  My MacBook Pro (2.4 Ghz, Santa Rosa with infamous nVidia card) acts strange. It shows the normal gray screen with Apple logo and animation flawlessly during start up but the internal display goes black without any rendering at all when all is loaded. (shining a light on display show nothing) If an external monitor is connected through the DVI port it will remain black during start up and then show the desktop as the internal display goes black. This happens both while booting to Mountain Lion and Windows XP. I have checked "About my Mac" and only the external display is listed. The same is the case if I use the nVidia Control panel in Windows XP. My questions: Is this a hardware problem or is it related to software maybe even firmware? What controls the display during start up, graphics card or something else?

• SHA-256 encryption wrong result in Android

  - by user642966

  I am trying to encrypt 12345 using 1111 as salt using SHA-256 encoding and the answer I get is: 010def5ed854d162aa19309479f3ca44dc7563232ff072d1c87bd85943d0e930 which is not same as the value returned by this site: http://hash.online-convert.com/sha256-generator Here's the code snippet: public String getHashValue(String entity, String salt){ byte[] hashValue = null; try { MessageDigest digest = MessageDigest.getInstance("SHA-256"); digest.update(entity.getBytes("UTF-8")); digest.update(salt.getBytes("UTF-8")); hashValue = digest.digest(); } catch (NoSuchAlgorithmException e) { Log.i(TAG, "Exception "+e.getMessage()); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } return BasicUtil.byteArrayToHexString(hashValue); } I have verified my printing method with a sample from SO and result is fine. Can someone tell me what's wrong here? And just to clarify - when I encrypt same value & salt in iOS code, the returned value is same as the value given by the converting site.

• Font Book does not Install all Fonts

  - by waiwai933

  My Mac decided to delete all but 19 fonts, which is fairly annoying. It didn't really delete them, as in I still have the original files in the /Library/Fonts folder, but they've disappeared from Font Book, so I can't use them. Now, Apple says that you can select a folder to install all fonts in that folder, but when I try that, the spinning wheel (not the beach ball) comes up in the lower right hand corner for a few seconds and then leaves, without installing any fonts. The same thing happens if I use the + sign in the menu bar, select multiple, or if I try validating and then installing (actually, that installs one font). Is there any way to mass-install these fonts or will I have to install them one by one? Comp info: Mac OS X 10.5.8 running Font Book 2.1 (123).

• App store for Windows

  - by Renaud Bompuis

  I'm wondering if there is any good App Store for Windows. I stumbled on allmyApps, and this question, but surely there are more out there. My dream Windows App Store would do things like: Allow me to download and install software Allow me to pay for apps Check which apps are already registered on my machine and keep track of them Keep track of all my machines Keep track of available upgrades and easily deploy them. Let me discover new apps that may be useful I know this is utopian on the Windows platform since development, upgrading, purchasing are so fragmented, but the Apple Store, Chrome App store, etc do make your life easier. Just trying to find something to ease the pain a little bit... So, are there any good services/software out there that would help me achieve some of the listed goals?

• Major permission repair needed on Mac Os

  - by Luke1111

  I made the fatal error of copying and pasting a sudo command into my terminal without double checking it, here it is. sudo -R mysql / What this does (for those that don't know) is recursively change the owner every file from the root down to mysql!! obviously not what i was intending This has of course played havoc with my system, the first thing i did was the apple permission repair but that only works for files that it has an idea of though it has changed a lot of file ownerships back to root. It seems that many library files are still owned incorrectly, as a lot of problems don't work. What i propose doing as a temporary fix until i can reinstall mountain lion is to recursively set all ownerships that are mysql to Luke. I'm not sure what they should precisely but this is still better than nothing. Is this possible using a shell script? I realise that this won't fix the problem properly and i will have to reformat but i need the machine in a workable state just for this week.

• FM Transmitter for the Home

  - by greggannicott

  After asking this question regarding piping music through my home I'm looking to buy an FM transmitter. I'd like to connect it to my home pc (ie. into the speaker port), and I'd then control the output with my iPhone (ie. using Apple's Remote software). The problem is, given that almost every FM transmitter is advertised to be used in the car (ie. an iTrip) it's proving very tricky knowing which one would be ideal for the home. First, has anyone tried this? Did it work ok or was there simply to much interference for it work. Secondly, if it did work ok, can anyone recommend a reasonable transmitter? For what I need it seems like an ideal solution, so given that I'm struggling to find information regarding it I'm starting to believe it's not as ideal as it first seems. Thanks in advanance.

• Howto update Preview.app from the command line without losing focus on OSX ?

  - by snies

  Hello, i want to update Preview.app in the background from the command line without losing focus of my current window. I know that i can use the following to open/update the view of a file, but than i lose focus to the Preview.app. open -a Preview foo.pdf I guess there might be some clever Apple Script commands to do so but so far i didn't find the right one. Alternatively i would be interested into transfering the focus back to my current app directly after the update. I need this in order to update Preview.app's view of a pdf through a vi autocmd after i update the pdf according to changes in a tex file i am editing. Here is an example of what i want to achive but using Ubuntu and evince.

• Is is possible to hide label colors in list view in Mac OS 10.X Finder? I use labels as star ratings

  - by Andrew Swift

  I have modified the first five label names in OS X Lion to be ? through ?????. This way I can easily tag photos etc. in the finder. However, I find that Apple's rendering of the colored bars is horrendously ugly. I'd like to keep the labels (to be able to sort by label) but not see the colors. I know it was possible to change the colors with Label X, but Unsanity has not issued an update for Lion. I don't need to change the colors, just find a way to hide them in the finder.

• Go back to 32-bit Java in OS X so I can use Chrome

  - by Mac Kris

  Recently Apple released a Java update. I mindlessly downloaded and installed it, thinking it must be good (I know that was stupid on my part). Now chrome doesn't work where sites require Java support. In terminal, java -version shows I have the 64bit version installed. I know Chrome does not support 64bit Java. I'd like to go back to the last version that worked for me, the 32-bit version. I don't want to use Safari or Firefox. I'd like Chrome to work. I have too much invested in customizing it to work with another browser.

• How to programmatically launch a chromecast app from command line

  - by pushmatrix

  I want to launch a Chromecast app but NOT using the chrome extension or iOS or Android. Doing this from command line. I noticed that you can send a POST to your chromecast, and it will launch an app. For example if I do curl -H “Content-Type: application/json” http://CHROMECAST_IP:8008/apps/YouTube -X POST -d ‘v=oHg5SJYRHA0' Then it will start up youtube. But for some reason I can't do this with custom apps (in dev mode). I thought I'd be able to send a POST to http://CHROMECAST_IP:8008/apps/MY_REGISTERED_APP_ID, but no luck. I just get a 404 response. Hmmm... My app is just a simple webpage (it is not streamed media). I want to run a little headless server that starts my chromecast app everyday via a CRON task. Any help is greatly appreciated! Thanks :)

• Typical text encoding and EOL behavior on mobile devices

  - by Dan W

  Typical things to worry about when dealing with text are the BOM/signature, encoding, and the end of line (EOL) char/chars. I know that Windows often favours \r\n (CR+LF) and Mac/Linux favours \n (LF), but how about popular mobile devices such as the iPhone and Android? Do typical apps on those platforms favour one or the other (or maybe even \r for iOS)? I'll supply both types to the user just in case, but I'd like to choose one as default. Also, which text encodings are mobiles most likely to use - UTF-8, iso-8859-1, Windows 1252 (or other default codepage) or maybe even UTF-16? And if they use UTF-8/16, are they likely to need (or require not having) a BOM/signature? What is the typical behavior here? Once again, I'll supply a range of encodings to the user just in case, but I'd like to prioritize or use certain encodings as default if it's appropriate.

• MacPro 1,1 video's card

  - by alexus

  I just bought a Mac Pro 1,1 from my coworkers and I'm looking to upgrade video card as the one inside is very noisy. What are my options? Basically I'm not looking to spend a lot of money, in fact i'd rather to spend as little as possible and get low end or mid range card, I'm not really playing games all that much so pretty much anything will do, I'd prefer 2xx series though. Current Mac Pro sells w/ GT120, Apple sells upgrade kit for $149 (which is okay, I just not sure if I'll be able to use this card on such an old Mac Pro)

• MacBook start up problem

  - by DA

  I have an aging, ailing MacBook. The battery died on it a few months ago, but can still use it when plugged in. I recently upgraded it to Snow Leopard. Had it unplugged for a few days. Went to boot it up today and now get this symptom: start up chime white screen with apple logo shuts off That's all it'll do. I tried unplugging and holding down the power button for 30 seconds but that didn't remedy the situation. Any theories? Finally an excuse to get the 27" iMac?

• Using international phone numbers on iPhone [closed]

  - by Cawas

  Spin off question Is it possible to hack a SIM card to add a javacard application on it (to properly format international numbers)? If yes, how? Original Question In my previous phone carrier I could just dial +55 11 99883655 and it would just work. Now I moved to a new carrier and it doesn't work anymore! When I dial the same international number it keeps saying the number isn't formated correctly. How can I get my iPhone to understand international numbering back again? I've got over 100 contacts with numbers stored in this format already, and I want to keep them that way. edit: I originally asked this question here, moved it to apple stackexchange and now I'm bringing a new one (hopefuly).

• Disabling multitasking on iPhone 3GS using UIApplicationExitsOnSuspend not working

  - by NobleK

  Hello I am developing an iPhone app where I don’t want/need the multitasking capability and I want my app to initiate every time I open it. I have set the UIApplicationExitsOnSuspend property in the info.plist and it does work when I test it on my iPhone 4 and in the simulator (which is also an ”iPhone 4”). The app calls applicationDidEnterBackground followed by applicationWillTerminate. However, when testing it on my wifes iPhone 3GS the property seems to be completely ignored and the program gets suspended/resumed. Both phones are running iOS 4.2.1. Someone has also confirmed this issue in another thread, with no solutions unfortunately: iPhone: how to test if UIApplicationExitsOnSuspend is working? Is there something I am missing to make this work? Any other ways to accomplish this? Thanx in advance

• Xcode 5 new bug

  - by user2874675

  Since the recent IOS update last month I have been having issues with this new bug that has hampered my program. The bug is as follows: using a UIButton and I want to insert a value into it, only after my execution ends does a letter actually appear. But if I create a method during execution to tell me, using NSLog, what my properties contain then that letter I added never shows up. I'm thinking I need to find a way to refresh a property during execution instead in the end. For example: Let's say you want to insert the letter F into a UIButton. Immediately after writing F into that UIButton, look to see that F hasn't isn't in there. But it will only show up after that particular execution sequence finishes. Any help would be great. Thanks in advance.

• Set resolution of unattached display in OS X?

  - by Brad

  I have an HDTV that I'm hooking up via DVI to HDMI from my Mac mini. In my struggle to eliminate overscan I managed to set the screen resolution to something not supported by the tv. How do I change the resolution without that screen attached? Specifically my tv says it's "720p and 1366 x 768 Resolution". The 720p resolution option in OS X made for a ton of overscan (couldn't see menubar or dock at all). So I tried something x 768 and managed to shoot myself in the foot with an unsupported resolution. I thought it was okay to experiment since a resolution change times out if you don't accept it. Apparently that didn't happen for some reason. I've already deleted the com.apple.windowserver.plist in /Library/Preferences as I saw suggested in other places, with no effect.

• Accessing English language reviews of iPhone apps

  - by Philipp Lenssen

  Hi! I'm on the creator side of iPhone apps so I'd like to read some of the reviews for our apps. However, because I'm German and don't have a US bank account, iTunes only shows me the German reviews. How can I see the US ones too? Trying to switch the account in my iTunes, Apple warns me that I need a US bank account, and that I have ongoing TV series subscriptions that can't be cancelled yet... and only offers a Cancel button.

• Colors less saturated in Snow Leopard Finder, Preview & Safari than in Chrome -- why?

  - by Andrew Swift

  If I look at the picture here in Safari, Preview or the finder, the shades of blue are significantly different than if I look at the picture in Google Chrome (they are less saturated than in Chrome). Since I am a photographer and need to prepare pictures for publication online, I need to know what a jpeg should really look like, in order to color-correct it. I have an excellent Eizo monitor that is correctly calibrated. If I open the same image in Photoshop CS3, I get the Chrome colors if I use Monitor RGB under view proof setup, and I get the Safari colors if I use Macintosh RGB. Can anyone explain the difference between these two settings, and the difference between Safari and Chrome? Which colors are correct? Photos that I prepared under Windows (during the past five years) now seem washed out in the Apple Finder and Preview, even though I had correctly prepared them. Is there a setting on the Macintosh for color calibration, besides the monitor calibration control panel?

• How Can I Set the OS X Dock to Show Instantly Instead of Waiting Half a Second in Snow Leopard?

  - by Patrik Björklund

  Having a MacBook Pro 13" I find myself trying to maximize the screen real estate constantly which have led me to put the dock at the right hand corner of the screen. Now in an attempt to save a few more pixels I decided to give autohiding of the dock a go and ran into a problem that have plagued me all night... When you toggle the switch to automatically hide the dock you get stuck with a small delay before it appears when hovering the edge of the screen. I have learnt that this is one of the many design principles Apple have put in use. In this case it appears to be their mission to save me from seeing the dock those few times when it's not intentional to touch the screens edge. In Windows there was a way to tweak this setting to have the menubar appear instantly by altering some registry value. Is there some way I can do this in Mac OS X?

• Snow Leopard crashes my Xerox printer

  - by Ho Li Cow

  Just set up 2 brand new iMac 21.5" with OS X 10.6.2 pre-installed in our office. Now whenever we try to print an e-mail out, it re-sets the printer i.e. it switches off, does a POST and prints out a Printer Config page. I can print web pages and from other apps fine, just Apple Mail seems to be suffering. Printer is a Xerox Phaser 7750. I downloaded the drivers it recommended when i first tried printing which didn't help and then also tried downloading from the Xerox site. The latter seemed to install fine but then right at the end, it would say 'Installation Successful', then ask me to choose a printer (it found it fine, both by Bonjour and Raw TCP - i tried both) and then it would give an error message. Any help appreciated.
