  • Can I use a 27" iMac as a additional monitor for another 27" iMac?

    - by Darren Newton
    I currently have a 27" iMac i7 with the 512mb ATI card. After looking at prices on other Apple displays it appears I can purchase another low-end 27" iMac (Core 2 Duo basic model) for less than a 30" display. 3 Part question: Can I easily use the lower-end iMac as an additional monitor to my higher end iMac? While I am using the lower-end iMac as an additional monitor can I still take advantage of its CPU to do things like run a webserver, compress video with Handbrake, etc? Are there any other 27" LCD displays with the same resolution (2560 x 1440) cheaper than the basic iMac (~$1699.00 US)? Any insights appreciated.

  • How do I find out what the Finder is busy with?

    - by Peter S Magnusson
    I'm running Snow Leopard on a MacBook Pro. My Finder has decided to be very busy, and neither restarting Finder nor a reboot cools it down. Spotlight doesn't report activity, Time Machine isn't busy, yet top -ocpu reports Finder is running between 30% and 100%. Update: none of the suggestions have worked. At this point (three months after first asking the question), I'm resigned to wait until the new MacBook Pro comes out and start with a clean install. Very frustrating that there's no way to investigate what the Finder gets stuck on.

  • Blocking ports in Airport Express

    - by gok
    I want to block torrent and other file sharing apps from Airport Express. How could I achieve this? I am not asking the port numbers. It's so sad that Airport Express is a very closed system. I miss my old Alcatel router in which every setting was possible.

  • Why does my MacBook Pro have long ping times over Wi-Fi?

    - by randynov
    I have been having problems connecting with my Wi-Fi. It is weird, the ping times to the router (<30 feet away) seem to surge, often getting over 10 seconds before slowly coming back down. You can see the trend below. I'm on a MacBook Pro and have done the normal stuff (reset the PRAM and SMC, changed wireless channels, etc.). It happens across different routers, so I think it must be my laptop, but I don't know what it could be. The RSSI value hovers around -57, but I've seen the transmit rate flip between 0, 48 and 54. The signal strength is ~60% with 9% noise. Currently, there are 17 other wireless networks in range, but only one in the same channel. 1 - How can I figure out what's going on? 2 - How can I correct the situation?

  • Powering-down USB Powered Devices on laptop sleep

    - by Carl
    I recently purchased a Targus Lap Chill Mat, which is a USB powered device, but doesn't have any interface/storage/etc function. I'd like it to power-down when my (macbook) laptop sleeps (since the fan obviously doesn't need to be running when the laptop is idle) without having to unplug it. Any suggestions?

  • Backup Gmail using Mail.app and IMAP without redundancy

    - by Cawas
    I don't care for actually using mail app, I use mostly the gmail interface and mail app just for offline, for quickly reading and eventually replying. Everything is working fine, I think I've followed every guide out there... Here's a great one. But I could find nothing about avoiding redundancy. Well, I can manually do that either by using POP or by checking off most of my labels out of IMAP. But I do use a lot of labels and I often label messages with more than 1 label. And I want them on mail app. Is there anyway to make it keep just 1 copy of repeated messages? Maybe there's a message id or checksum that could be used... If there isn't a way to do it, be assured I still prefer having the extra messages and "wasting" space rather than not having any. edit: I've came across many solutions for finding duplicate files, but they just delete the files. That just make things worst: Mail will just sync it all again. I've realized it's probably better to keep two accounts setup, POP for backup and IMAP for everything else with removing the "All Mail" from it. That's because if the "All Mail" on the server is deleted for any reason, my "All Mail" local will also get deleted, while POP will keep all files regardless of the server. This doesn't solve the redundancy issue at all, but it doesn't create any new issue as well, and I can even use the search properly, without duplicated results, if I search just on the POP. So it helps optimizing a little bit. But I still think the best way to solve this issue would be having something such as aamann's Mail Scripts tweaked to hardlinking the duplicates rather than deleting, and optimized to not need to scan everything every time. I'm trying to contact him and see what we can do. At any pace, I'm still looking for an answer!

  • MAMP Pro Uninstaller Throws "The privileged action failed." Error Even After Entering Password

    - by BigM
    I have followed, and successfully completed, every step in this SO article to remove MAMP Pro in favor of installing the free version as I only need it for one site anyway. However, when I run the uninstaller I still get "The privileged action failed." after providing the password. Can anybody shed a little light on this maybe? I'm just trying to get MAMP Pro uninstalled so I can install the free MAMP stack.

  • Bash on Snow Leopard doesn't obey terminal colours

    - by karbassi
    With the new version of Snow Leopard, OSX upgraded the bash version to GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin10.0). Now, my .bashrc sets the following settings: # Colors export TERM=xterm-color export GREP_OPTIONS='--color=auto' GREP_COLOR='1;32' export CLICOLOR=1 export LSCOLORS=ExGxFxDxCxHxHxCbCeEbEb # Setup some colors to use later in interactive shell or scripts export COLOR_NC='\e[0m' # No Color export COLOR_WHITE='\e[1;37m' export COLOR_BLACK='\e[0;30m' export COLOR_BLUE='\e[0;34m' export COLOR_LIGHT_BLUE='\e[1;34m' export COLOR_GREEN='\e[0;32m' export COLOR_LIGHT_GREEN='\e[1;32m' export COLOR_CYAN='\e[0;36m' export COLOR_LIGHT_CYAN='\e[1;36m' export COLOR_RED='\e[0;31m' export COLOR_LIGHT_RED='\e[1;31m' export COLOR_PURPLE='\e[0;35m' export COLOR_LIGHT_PURPLE='\e[1;35m' export COLOR_BROWN='\e[0;33m' export COLOR_YELLOW='\e[1;33m' export COLOR_GRAY='\e[1;30m' export COLOR_LIGHT_GRAY='\e[0;37m' The colours are used later on for output. This used to work in previous version of OSX but not my output is as such: Some ideas that have not worked. Switching Terminal.app from 64-bit to 32-bit.

  • OS X not booting after upgrading LibXML2

    - by Federico
    I tried upgrading the version of LibXML2 in my machine to run some propietary software. Compiled as 32-bit (-arch i386) and restarted to see if it worked. Now when I try to boot I can only get into the spinning screen and it just sits there. Restarting in verbose mode (Cmd-V) does not show any error in the process, it just freezes after "AppleIntelCPUPowerManagement: initialization complete". I can't from any CD either (if I press c on startup it just spins the disk around and then stops in the same spinner screen). I've also reset the PRAM/NVRAM to discard any problems with that and it´s still not fixed. Any pointers of what might´ve gone wrong? (Latest gen MBP, running 10.6.3)

  • Can I delete EFI System Partition without harming other data on drive?

    - by Andy
    I have three external HDD's in a USB enclosure. After a recent upgrade to Win7, during which these three drives were actually installed inside the PC tower, two of the three drives now have a 200MB EFI partition, and the two drives do not show up as usable drives under either Win7 or Snow Leopard. One of the drives is empty; the other one, however, has a bunch of stuff on it that I want to save if possible. My question is, how can I get back to this data? Can I simply delete the EFI partition, and all will be well? Or do I have to do something trickier? Or am I just hosed?

  • Default Text Color in Apple Mail.app

    - by Axeva
    Is there any way to set the default font color for new messages in Mail.app? It's trivial to set the actual font, and text size. I cannot seem to get the application to change the text color though. It always defaults to black. After 5 or 6 major revisions of OS X, surely someone has thought of this, right?

  • Unable to authenticate Windows XP clients agains Snow Leopard Server PDC after 10.6.2 upgrade

    - by Roland
    I have setup a Snow Leopard Server 10.6.1 as a PDC without problems to authenticate Windows XP clients. Joining a Windows XP client to the SLS PDC Domain and log in from a Windows XP client to the SLS PDC Domain are working. After the update to Snow Leopard Server 10.6.2 the authentication is broken. opendirectory_smb_pwd_check_ntlmv1 gave -14090 [eDSAuthFailed] By changing the Windows XP "Network security: LAN Manager authentication level" policy to NTVLM2 responses only the authentication agains a SMB share is possible, but trying to join SLS PDC Domain is still not possible. opendirectory_smb_pwd_check_ntlmv2 gave -14090 [eDSAuthFailed] Any ideas? Is anyone else having similar authentication difficulties?

  • What’s the password for my FileVault 2 boot volume?

    - by cbowns
    Apple’s support document for FileVault 2 (a.k.a. “full disk encryption” or “FDE”) has lots of information about enabling FDE and what it means for booting the machine. However, it doesn’t cover one very important thing I’m trying to do: mount the drive in the Recovery HD environment to reinstall OS X on it. The Recovery HD environment asks me for the volume passphrase so it can mount my drive and try to install OS X onto it. If this were an external drive which I’d manually enabled FDE on with diskutil, or an external Time Machine volume, I’d know it because it makes you pick one (just like a regular login password), but FileVault 2 never asked me for a volume passphrase (I assume it selects one behind the scenes). I’ve tried my main user’s password, but that doesn’t work, and neither does the recovery key set for the volume. Keychain Access doesn’t have anything that I could find. How do I unlock this volume?

  • Ad-hoc connection between iPhone and Macbook Pro

    - by Phil Nash
    I sometimes find it useful to connect my iPhone to my Macbook Pro by creating an ad-hoc wireless network from the MBP and connecting to that from the iPhone. However, what I find is that sometimes this works and sometimes it doesn't. When it's not working the symptoms are usually that I see the ad-hoc SSID in the list of available networks on the iPhone, can connect to it from there (including entering my WEP key), and it shows up as the wifi network in use. However I don't get the wifi symbol in the taskbar (it remains as 3G) and attempting to use the connection (e.g. trying to connect to iTunes or Keynote using their respective Remote apps) fails saying that there is so wifi connection. I've tried rebooting both the iPhone and the MBP, recreating networks with different SSIDs and tried different channels - all to no avail! I'm especially puzzled that (a) sometimes it works just fine first time and (b) the Settings app seems to think its all connected fine. Is there anything else I should be trying?

  • opening socket to google hangs on SYN_SENT

    - by puchu
    I have 2 computers now: downloader (asus at4nm10t-i) with debian and desktop (asus sabertooth 990fx) with gentoo in the same network under NAT even with the same ethernet card: RTL8111E. driver r8169 is compiled as module on both computers. Sometimes in evenings desktop cannot connect to google and all its services like now: curl -v http://www.google.by on downloader it received server's answer immediately. on desktop it hanged and when I ran in other terminal: netstat -ntp | grep curl >>tcp 0 1 192.168.0.7:54126 173.194.35.191:80 SYN_SENT 4876/curl after 1-2 minutes it received server's answer. I was tried to change ip of network, mac address of desktop but nothing changed. When I was trying to connect to another services except google: curl -v http://www.yahoo.com both computers received answers immediately! Only when I rebooted desktop it begins to work with google services correctly I cant understand what is this bug related to. In which bugtracker should I post this: r8169 or linux kernel or google? PS. Desktop was checked with memtest: 5 passes - no errors

  • PECL install error after upgrading to OSX 10.8

    - by Clive
    I've just upgraded my OS to Mountain Lion and PECL is no longer working (it's on a test drive so no drama, but I'd like to get it working so I can upgrade the OS on my shiny new SSD as well). I'm using the native PHP installation, no macports/homebrew or anything like that. Running sudo pecl install uploadprogress (for example) produces the following terminal output: downloading uploadprogress-1.0.3.1.tgz ... Starting to download uploadprogress-1.0.3.1.tgz (9,040 bytes) .....done: 9,040 bytes 4 source files, building running: phpize grep: /usr/include/php/main/php.h: No such file or directory grep: /usr/include/php/Zend/zend_modules.h: No such file or directory grep: /usr/include/php/Zend/zend_extensions.h: No such file or directory Configuring for: PHP Api Version: Zend Module Api No: Zend Extension Api No: autom4te: need GNU m4 1.4 or later: /usr/bin/m4 ERROR: `phpize' failed I'm guessing the problem is the 3 grep lines. I've found several threads that suggest this is caused by XCode not being installed...but XCode is installed, and updated to the latest version (4.4). All the relevant symlinks to /Developer/usr/bin/* also exist as they should. m4 is currently at version: m4 (GNU M4) 1.4.13, so even though the output above contains a line pertaining to it, I don't think that can be the problem. I'm sure it's just a simple issue, anyone got any clues?

  • How do I make dashboard widgets active on logon?

    - by CharlesB
    There are a few dashboard widget that are useful even when not going in Dashboard. For example, SVN Notifier sends a Growl notification when commits are made to a repository you want to watch. Or, Delivery Status does the same for status update on tracked packages. The thing is when I log into OS X, those status updates won't happen until the first time I actually enter into Dashboard, so it looks like they are not initialized at startup. How to fix this?

    - by Mike
    My question is for my girlfriend basicly.... She works at a mall and doesn't do much so she likes to get on myspace and facebook as most girls do and yahoo to check her email. Well she uses her laptop to connect to a wireless network that doesn't allow it.... so I did some research and got putty and connected to my linux box I have here at home and it worked somewhat. My problem is it only views my webpages I have created here on this box it won't go outside of the linux host. I did it like this in putty... port is 1000 and hostname:80 is what I got outa my research then connected after seting up the tunnel bam worked for all webpages on my box but when she puts in www.myspace.com it redirects to my index.php in my var/www and won't travel outside that as I said.. Any help would be much obliged.

  • Stop a runaway launchd process on OS X Leopard

    - by Skylarking
    I created a launchd .plist file to in order to have a python script run every hour. I ended up editing and later deleting the .plist file ( in /Library/LaunchDaemons )... but somehow launchd is still trying to run the script.. The file that the original .plist was calling is also no longer present ( it was in /usr/bin ).. Now every 10 seconds launchd is still attempting to run the script, fails, and respawns... I tried fixing this with Lingon.... to no avail.. Is there a way to kill this process for good? I tried logging out and restarting as well... Machine is running 10.5.8

  • Local area network computer to computer backup software

    - by thegreyspot
    Hi! I would like to back up my other computers on my local home network to my computer. What software would you suggest? I liked crashplan, however their confusing UI, and its ability not to sync, turned me away. But it has the right idea.
