  • Prevent outgoing traffic unless OpenVPN connection is active using pf.conf on Mac OS X

    - by Nick
    I've been able to deny all connections to external networks unless my OpenVPN connection is active using pf.conf. However, I lose Wi-Fi connectivity if the connection is broken by closing and opening the laptop lid or toggling Wi-Fi off and on again. I'm on Mac OS 10.8.1. I connect to the Web via Wi-Fi (from varying locations, including Internet cafés). The OpenVPN connection is set up with Viscosity. I have the following packet filter rules set up in /etc/pf.conf # Deny all packets unless they pass through the OpenVPN connection wifi=en1 vpn=tun0 block all set skip on lo pass on $wifi proto udp to [OpenVPN server IP address] port 443 pass on $vpn I start the packet filter service with sudo pfctl -e and load the new rules with sudo pfctl -f /etc/pf.conf. I have also edited /System/Library/LaunchDaemons/com.apple.pfctl.plist and changed the line <string>-f</string> to read <string>-ef</string> so that the packet filter launches at system startup. This all seems to works great at first: applications can only connect to the web if the OpenVPN connection is active, so I'm never leaking data over an insecure connection. But, if I close and reopen my laptop lid or turn Wi-Fi off and on again, the Wi-Fi connection is lost, and I see an exclamation mark in the Wi-Fi icon in the status bar. Clicking the Wi-Fi icon shows an "Alert: No Internet connection" message: To regain the connection, I have to disconnect and reconnect Wi-Fi, sometimes five or six times, before the "Alert: No Internet connection" message disappears and I'm able to open the VPN connection again. Other times, the Wi-Fi alert disappears of its own accord, the exclamation mark clears, and I'm able to connect again. Either way, it can take five minutes or more to get a connection again, which can be frustrating. Why does Wi-Fi report "No internet connection" after losing connectivity, and how can I diagnose this issue and fix it?

  • Mac has become insanely slow : Processes SystemUIServer, UserEventAgent and loginwindow using a lot of memory

    - by SatheeshJM
    I have been using my Mac for for many months without any problem. But recently all of a sudden the Mac became insanely slow. I opened Activity Manager to see what was happening. For three processes SystemUIServer, UserEventAgent and loginwindow, the memory gradually increases and reaches upto 2 GB for each process. This completely hangs up my Mac. I tried the following : 1. Restart Mac 2. Restart Mac in safe mode 3. Manually kill the processes 4. Remove Date and Time from Menu bar(this was supposed to be the problem for the SysteUIServer process's memory according to many users) 5. Removed the externally connected keyboard and mouse(some had suggested this for UserEventAgent's memory) No luck with any of those. The moment I log in, the memory spikes up. Any idea what the hell is happening? Please help.

  • Launchctl: how can I configure a service to stop restarting automatically until next reboot?

    - by Andrew J. Brehm
    I have several services set up in launchctl and they all start at boot and restart automatically whenever they stop for any reason. That's great so far. But sometimes I want one of the services to quit and not restart for a while. Is there a recommended way to do that apart from removing the service from launchctl (which also stops it immediately, which I don't want to do)?

  • Drive Genius says: "Invalid catalog btree reverse link in node" is this fixable?

    - by bencnscp
    No obvious problems with my Mac OS X 10.5 system, but Drive Genius 1.5.1 says: "Invalid catalog btree reverse link in node" when doing a "Verify" The "repair" and "rebuild" options fail. I did some googling, and the consensus as: 1- Drive Genius is slightly better than Disk Warrior 2- This problem is likely not fixable. My assumed solution is that I should do a full backup and re-format.

  • One USB flash drive to rule them all

    - by Chris
    Yesterday I purchased a 32GB USB flash drive. I have a myrid of systems in my home, and would like to have one flash drive with setup files for all the various systems throughout the house. I kept the Fat 32 filesystem on the drive, as I figured that is probably the most universal. I then made the partition bootable using fdisk. I then copied the Windows 7 setup files to the drive. I then installed grub 2 (1.98) onto the drive using backtrack 5. I was then able to load the windows 7 setup / install from the flash drive on an older BIOS type motherboard. Now I would like to know how to get this to work on my MacBook Pro 8,2 with still retaining support for legacy computers. Is this possible, or is this just a pipe dream. I plan on getting OS X on the drive, gparted, and OS X86 on the drive when all is said and done. I've done various google searches but really haven't found a guide on how to setup a swiss army usb flash drive.

  • Apple Automator "New PDF from Images" maintaining same filename

    - by mech
    I will potentially have 26k of old legacy PICT images to transfer first to PDF for migration. I am using Apple Automator and also the "Dispense Items Incrementally" to loop through it. However, I can't seem to let "New PDF from Images" to remember the original filename. Anyone able to offer some advice :) FYI, I am transforming it to PDF because I can't do it using ImageMagick to convert directly to my ultimate JPEG format. Due to the fact that my PICT was created very long ago and thus has some convert: improper image header error. See this ticket for more information. Thus I am doing a intermediate convert PICT to PDF first, then convert that PDF to JPEG :) The only thing left is the naming of the "Output File Name" which do not allow me to identify original filename. See the screen here:

  • Why is Safari on my computer rendering all of the colors -- not just for images -- incorrectly?

    - by richardhenry
    I’m not just talking about image color profile issues; every single color that the browser renders is incorrect. It’s like it’s in it’s own color space (or something!). Screenshot: http://drp.ly/DJk1O (Opera, Safari, Chrome, Firefox) Spot the odd one out? Open this up in Photoshop or similar and try using the eyedropper to select the colour. Safari renders the same hex color completely differently. That color is set using a background-color declaration in CSS, so it should be identical in all four of those browsers. Here’s the HTML I was using: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>untitled</title> <style type="text/css"> body { background-color: #114742; } </style> </head> <body> </body> </html> Literally every website I’m viewing with my install of Safari is displaying colors incorrectly. The blue of the bar on Facebook is slightly less rich. This doesn’t occur on any other Macs I’ve tried. Any idea what’s happened to my Safari install?

  • How do I compile DarWINE in PowerPC Mac OS X 10.4.11...?

    - by Craig W. Davis
    So far I've tried using MacPorts which gives me this error: /Error: Cannot install wine for the arch(s) 'powerpc' because Error: its dependency pkgconfig is only installed for the archs 'i386 ppc'. Error: Unable to execute port: architecture mismatch To report a bug, etc... (I'm not allowed to post two links due to being a new poster...)./ I've also tried using the build script I found in the DarWINE 0.9.12 SDK download that I found on the DarWINE SourceForge.net Project Page... I've also tried the build script that I found at http://code.google.com/p/osxwinebuilder/#Building_Wine_via_the_script... None of these attempts to build DarWINE have actually worked. Whenever I build using the DarWINE build script I run it as follows: /1. I decompress the WINE tarball into ~/Downloads/WINE 2. I cd into ~/Downloads/DarWINE. 3. I run ./winemaker ~/Downloads/WINE/wine-1.2.2 or ./winemaker ~/Downloads/WINE/wine-1.2-rc2 (the reason for trying WINE 1.2-rc2 is that some people managed to get it to build on PowerPC Macs running 10.5.8...)./ I made sure to install Xcode Tools 2.5 & all the SDKs too... The net result is either a syntax type error resulting from trying to run the checked out Google Code DarWINE build script or a bunch of make errors when trying to run the official DarWINE build script that I forcefully extracted from the DarWINE 0.9.12 SDK .dmg file by using Pacifist. I trying to build DarWINE on mid-April 2006 1.42 GHz eMac with DL SuperDrive with Bluetooth 2.0+EDR with 2 GBs of RAM running 10.4.11 as I mentioned earlier... (it came with 10.4.4 on the Mac's Restore DVD-ROM that I ordered from 1-800-SOS-APPL & coconutIdentityCard told me it was made on April 12th 2006 & I know that's right because when I reinstalled Mac OS X 10.4.4 it displayed that it was registered/previously owned by a Hawaiian school...): /make[1]: winegcc: Command not found make[1]: * [main.o] Error 127 make: * [dlls/acledit] Error 2./

  • Automatically enable Xcode "Developer Mode" on computer lab workstations

    - by smokris
    After reimaging a computer lab workstation, the first time a user tries to build and run an Xcode 4 application, Xcode pops up the "Enable 'Developer Mode' on this Mac?" prompt, requesting an administrator password. How can I automate this process (via a script), so that I don't have to go around to every workstation, create a new Xcode project, build and run it, and enter the admin password each time the workstations are reimaged?

  • CDROM does not appear on desktop, MACOS 10.5.7

    - by Cheeso
    When I pop a CDROM into the drive of my Macbook Pro, It spins up, I hear it, but no icon appears on the desktop. (I think it's 10.5.7; actually not sure how to verify this on Mac, but I think I saw a 10.5.7 flash by somewhere). In the finder preferences, I have "Show these items on the Desktop" set to show HDs, External Disks, and CDs, DVDs, and ipods. All three of those are checked. I do see the internal HD on the desktop. In Disk utility I can see the CD/DVD hardware. It says "MATSHITA DVD-R UJ-857E...". From Disk Utility I can eject the drive. But in Finder, there is never a CD/DVD listed under "Devices". When I insert a disk, nothing happens, I cannot see it. I also cannot boot from bootable CDROMs by holding C down . Suggestions? I am not very experienced with Mac; I have used Windows for years. EDIT Two updates: I saw this article on support.apple.com, and modified the hostconfig appropriately. It did not have the AUTODISKMOUNT entry, so I added one, rebooted. Same behavior. It does not see the CDROM in Finder, does not mount it on desktop. I put an old manufactured CDROM into the drive, and voila! it showed up on the desktop. The CD that does not appear is a GNome Partition Editor Live CD, which I guess is based on debian. That CD boots in other (non-Mac) PCs. I want to use this to adjust the Bootcamp partition. Suggestions?

  • OS/X Mavericks won't download in App Store

    - by Mike Christensen
    I tried to download OS/X Mavericks through the App Store yesterday. However, I had to leave work before it was done downloading and shut down the machine while it was downloading. I assumed I'd be able to resume the download, or start over again later. However, now there's no way to get it to download again. When I find OS/X Mavericks in the store, I click on the "Download" link. It asks for my Apple ID which I enter, and it does absolutely nothing. It doesn't begin downloading, and it just still shows the "Download" button. Clicking on it again does nothing. I'm thinking there's something stuck somewhere, like some flag that says this download is in progress or it has already been downloaded. Is there some way to clear that out so I can start downloading it again?

  • Bash window title not restored after exit

    - by forthrin
    I have a problem with the window title in the Terminal window on OS X: Start Terminal. Window title is "bash" Type "ssh external" to connect to an external server. Window title is "user@external:~" Type "exit". I am now back at my local machine, but the window title still says "user@external:~". How do I make the window title return to "bash", which I assume would be correct since I have logged out of the external server and returned to my local machine? My ~/.bash_profile has the same PS1 value: export PS1='\w$ '

  • Utilize different region format for a single application on Mac OS X

    - by Jeff Hellman
    Is there a way to have a single Mac OS X application utilize a different region format than the system default? For example, I'd like to keep my system operating in English with US date formats but have my lesson planning software utilize French date formats. If I put my entire computer into French mode, I get the desired results, but I'd rather keep my entire system in US mode and have the Planbook application work with French region formats. I know about Language Switcher but that only allow per-app selections of localizations to be used, not which date format to use. I don't care about having the French localization of Planbook appear, I just want the date format to be French.

  • What's the easiest way to migrate one Mac OS X volume to another

    - by teabot
    I want to move a volume from a smaller drive to a larger unformatted one. What is the best way to achieve this? Ideally I'd like the new volume to have the same name as the older volume as it contains user accounts, and is a destination of various symlinks that I have on other volumes. Update: I used Carbon Copy Cloner in the end and it worked perfectly. I was able to simply rename the new volume in Finder to the same name as the old volume and then powered down and removed the old drive on which the volume lived. When I restarted, the new volume seamlessly worked in place of the old volume.
