Snow Leopard doesn't redetect display after partial standby
Hi, I'm using a Mac Mini in a home theater PC setup. I run Plex on the Mac. When I shut down the theater, I turn off the projector and amp, but leave the Mac on. I have it set to never automatically go to sleep, though I do let it spin down the hard disk. I've tried quitting Plex and leaving it running.
My problem is that when I turn the projector and system back on, most of the time (but not always) I get a message from the projector that it's not detecting any signal. I can ssh and remote desktop into the machine, but cannot figure out how to force it to realize a projector is attached. I normally run the projector in 1920x1080 resolution, but when I remote desktop in, I can see that it's defaulted back to 1680x1050 resolution.
I've tried 'kill -HUP' to the WindowServer process, but that also doesn't help.
Any ideas of something I can do to force the mac to realize a projector is connected? Cmd-line, applescript, or a Mac app would all be fine. I never noticed this issue when I was running Leopard.
thanks!
Hi, the problem still persists for me. I've tried disconnecting and reconnecting the DVI cable from my MacMini, and that at least causes it to send something to my projector, but it's a bad signal that my projector can't display.
Are there any command-line tools for figuring out what's happening with the display output? Are there any ways I can force a full re-detect? If no to both of these, what's the right way to file a bug that an engineer at Apple would read (other than emailing friends who work there)
thanks again!

iPhoto6 on iMac running SL - after a full reistall of Snow Leopard, iphoto does not display thumbnails. I've restored the library from time machine, rebuilt the library from iPhoto and run through the rebuild thumbnails function with no success. The files are there, I just get a dotted outline instead of the thumbnails. Does anyone have any other ideas on how to restore the thumbnails?
Try the following:
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Hi,
I purchased our iMac 4 with Tiger OS X some time ago (2007) and until recently had absolutely no problems....and then, we met the Snow Leopard. I added the 2GB of memory without a hitch. Backed -up what needed to be backed up to an external hard drive, check. When I tried to install the Snow Leopard disc, it would only install partially or not at all and after almost 16 hours of trying to figure out where I went wrong, I took it to the Apple Store. They said our "antique" slot disc was malfunctioning (only playing CDs because of the different laser calibrations) and they performed a clean installation of Snow Leopard by external USB drive. Ever since we got the computer home it has been a NIGHTMARE! The computer freezes constantly. It runs much slower than before we performed the upgrade (even with an out dated Tiger!!), sometimes it doesn't even boot completely, leaving only the white screen and I'm going crazy! Finally, I get on to Safari without it freezing 15 minutes after loading (angles singing) and tried to purchase a software that will copy my iPod to the new iTunes. An error popped up politely stating that I had made a "BAD REQUEST - Your browser sent a request that this user could not understand. Reason: Your speaking plain HTTP to an SSL-enabled server port. Instead, use the HTTPs scheme to access this URL, please." Since he asked nicely, I clicked on the supporting link for more information. Now there is another error message "Your copy of Safari is missing important software resources. Please reinstall Safari". I have gotten this message twice before.
I know I can always take it back to the Apple Store, however, if I can try to diagnose the problem myself and save the strain of throwing it through the Apple Store's window causing a frustration inspired ruckus, I'd consider it a good day. Does anyone have the slightest idea what might have gone wrong? And is it really worth the aggravation (or apprehension hehe!)? Should I throw in the towel and purchase another one?
Any help or input would be graciously appreciated!!Sorry for your pain! I would say since you have an open case with the Apple Store (they did something you say had a worse effect than before) you have a right to go back and continue, I would think. We could try to sort it out but it sounds like it could be fairly complicated. Four years old isn't that terrible, but it's not surprising to hear of CD drive problems. I think it is worth another trip back. Then you'll know better if it's time to buy new. And a refurb is cheaper than one of those plate glass windows!

Ok, tried message boards everywhere to try and figure this out before having to post a question. Have a 21.5" iMac running Snow Leopard 10.6.8. After updates no wireless capability for ipad or laptop, imac connects fine but nothing else. No dashboard widgets work, Skype won't work. What goes?
Your post is pretty lengthy and I have to admit I didn't read it all. Please try restarting in Safe Mode, if that doesn't work please do both a SMC and PRAM reset. These may take 2-3 attempts.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys. -
My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard. I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host. But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning. I can't get it to run Hardware Test - just get the white screen. If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

Perhaps you installed the wrong version OS X onto the iMac, you can't use the disk from another Mac.
clean the disk.
If it's not working then use this method to create a bootable 10.6 USB from the iMac machine specific 10.6 disk or the 10.6.3 retail disk on your other Mac, use it to boot the iMac with.

Preview.app in Snow Leopard doesn't open some jpg files
Preview.app in Snow Leopard doesn't open some jpg files.
Preview does't issue an error message, it behaves as I did't try to open file at all.
These images could be easy opened in iPhoto, so files seem to be OK.
I couldn't attach one such example image to this message, it's exceeds 2mb limit, but courtesy to google image could be downloaded by the link https://docs.google.com/leaf?id=0B56gs1tsb9aNYjA2MDdmNzUtOWY3NS00ODg1LWIzZDAtYTA 5YzFjZmZjYjRh&hl=en_US.
What's that? Should I file a bug?
ValeriyUnfortunately, it sounds as if your internal disk failed (hardware failure).
Things to try:
(1) Boot from your Apple Hardware Test CD/DVD, which sometimes is a separate disk or sometimes is on the original OS install disk. Run the tests, all of them, to see what is amiss.
(2) Reset PRAM as described in http://support.apple.com/kb/HT1379 . I don't think this is likely to help because even though your startup disk is not being selected, it seems that your internal disk is simply unable to be found or mounted, implying hardware failure more than software. But it's worth a try.
Probably time to take your computer in for repairs, either at the Apple Store or to an authorized Apple repair shop. Most likely they will simply replace your drive. You could also ask them to mount the old drive in an enclosure to see if files can be copied from it if you don't have a backup. -
Before I install snow leopard, I tried to move tiger into the external harddrive. My mac says it can't do because it is the OS X. So I installed snow leopard without removing tiger. After that, my computer often freezes. How can I remove tiger? Or How can I prevent my mac from freezing?

When you installed Snow Leopard, Tiger was replaced, leaving your programs and files intact.
What is causing your freezing problem is unknown, you can take Kappy's advice and remove everything, but you lose your files and free iLife programs that came with Tiger/new machine.
The 10.6.3 disk you "upgraded" with has the full 10.6.3 on it, but no free iLife suit, so a erase and install will remove what you already have installed.
You can try to locate your problem without the erase and install method by running through this list of fixes.
Step by Step to fix your Mac
But before you do anything, backup your personal data off the machine to a extenal drive and disconnect.
Most commonly used backup methods
Because if you have to follow Kappy's advice and wipe and install 10.6 fresh, it will cure your problem in nearly 99% of cases, but you have to rebuild everything. All programs and files.
How to erase and install Snow Leopard 10.6
If this is all too much for you, then STOP and call a local PC/Mac service or competant friend to assist you.
Yuo might need to install more RAM into the machine to make 10.6 run better as well. -

Reinstall with format
Utility disc on boot cd (scan disk & rights repair)
Even when I try to boot cd without second screen, I ve white screen
(after a update to 10.6.4)
Help me pleaseHi Tony,
I don't how these instructions are the same, here is what the article says:
_Resetting PRAM and NVRAM_
• Shut down the computer.
• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
• Hold the keys down until the computer restarts and you hear the startup sound for the second time.
• Release the keys.
Your original post said *"Restart the mac and depress the alt, command, P and R keys simultaneously. You should hear the boot chime. Keep the keys depressed until you hear the boot chime a further three times. On the final boot chime release the keys and let the mac boot normally."* How I understand your post that totals 4 chimes vs. the 2 Apple specifies. Am I missing something?

Snow Leopard killed my vga displays!!
This is by far the most weird problem I have ever encountered after upgrading to a new OS.
I run a company where we have something like 15 different Macs. Mostly Intel, but different ages, Mac Pro, Macbook Pro, iMacs, Mac Mini etc.
A couple of days ago I wanted to upgrade one of the Mac Pros to Snow Leopard. It's an early 2008 3.1 with ATI hd 2600 graphics. I wanted to do a clean install, but instead of backing up everything from the system drive, I pulled it out and put in a new clean one. This way I could retrieve the data from the old drive when I need it through a USB docking station or something.
Installation went by fast and without any problems what so ever.
But first thing I noticed when the first bootup was completed was that the resolution of my monitors were suddenly completely wrong. I have two Samsung Syncmaster 2343nw monitors connected through vga, and they have always been detected and automatically been set to the correct resolution in the display preferences dialog by the old Leopard. I have around 9 of these monitors working as dual displays on Leopard machines, and a few working as extra external monitors for a couple of Macbook Pros running both Snow Leopard and Leopard. They are all connected via an dvi to vga converter and they always get detected correctly as "Syncmaster" in Display preferences.
But suddenly now, they just show up as "VGA Monitor" in Display preferences.
After fighting with this for a couple of hours trying all the suggested workarounds I could find, zapping PRAM deleting /Library/Preferences/com.apple.windowserver.plist changing the cables and so on, I finaly gave up. Fortunately I didn't overwrite the old Leopard installation so of cause I could just swap the drives back and everything should be dandy after booting back into the old Leopard install.
But **** no! Now the resolution was equally messed up in Leopard! And none of the two monitors were detected as "Syncmaster" in display pref. Now they only show up as "VGA Monitor" as they did in Snow. ***?? How can an OS mess with a monitors plug 'n' play capabilities?
I then tried the obvious which was to try and reset the monitors, remove power from them, Zap the PRAM again. I even tried a different graphics card (that didn't work in this machine) but what ever I did, the monitors where no longer detectable by the OS.
Next step was to take some identical monitors from a different machine. And yes, they where detected by Leopard on the problem machine. Since I couldn't believe that Snow had actually ruined the other two monitors I booted back into Snow hooping that it would now detect these other identical monitors. But no, same problem. Back to Leopard, and once again now suddenly these couldn't be detected by Leopard either.
I have since tried these monitors on all the other Macs I have in the company, and only one machine with an nVidia card is able to detect them correctly as Syncmaster. But none the less also this machine isn't able to see the monitors native resolution thus making it impossible to select the right setting for the monitor.
So now I have 4 monitors that's virtually unusable after being in contact
I have read a lot about people who who suddenly can't use their secondary monitor after upgrading to Snow Leopard and that Apple is aware of this, and that 10.6.4 should address this problem when we finally get some new graphic drivers. But I haven't heard about anybody who's monitor lost it's plug 'n' play capabilities after being in contact with Snow Leopard.
But maybe someone here has had any similar experience? Maybe somebody else has had luck with upgrading a dual vga monitor system to Snow Leopard? I would love to get some ideas on what happened since these monitors doesn't really work anymore on any computer.
Thanks!Hmm... I know that the screens native refresh rate is at 60 Hz and the resolution is 2048 x 1152. I'm unable to check it out now but I'm pretty sure I can't select 60Hz. They only have VGA connectors (the same as D-Sub I guess?) And the closest I can get to the right resolution is 1920x 1280 (or maybe it's 1200, not sure) which looks almost right, but then again not, and a whole lot more fuzzy than it used to be.
On some machines the displays are detected as "Display" and on others "VGA monitor" or "VGA display". It's supposed to detect as "Syncmaster". Nothing changes if I press "Detect". I've only tried on machines running 10.5.8, and one brand new iMac running 10.6.3 through a display port to vga converter.
But thanks for link to the toms article. I'll give it a read -

Snow Leopard doesn't reconize my iPhone
Hi Everyone...
Well. After installing Snow Leopard on my MacBook Pro, iTunes is not able to find my iPhone - It doesn't even show.
I wanted to use my iPhone for internet as i once could, but since my MBP can't show it, all it does is charging battery...
Any one having the same problem??HI,
Try repairing disk permissions and see if that helps...
Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.

ADmtiMac v5 is not supported on OS X 10.7, Lion. If you have already upgraded to Lion, the incompatibility can cause a situation preventing you from logging in to any account. To remedy this situation, please follow these steps:
NOTE: If you do not feel comfortable performing these steps, please contact our Support Specialists for further help.
1. Restart the computer holding down the Command+S keys. This will start the system up in Single User mode.
2. At the prompt type the following commands (these commands will be listed above the prompt just in case you need to reference them):
/sbin/fsck -fy {hit the return key}
/sbin/mount -uw / {hit the return key}
3. Modify the /etc/authorization. At the prompt type
vi /etc/authorization {return}
This opens the file in the vi editor. Then type:
/AMHomeDirMechanism {return}
This searches for the first occurrence of AMHomeDirMechanism (case-sensitivity is important).
do this:
dd (don't press return, this deletes the line the cursor is on)
n (don't press return, this searches for the next occurrence of AMHomeDirMechanism)
until there are no more occurrences of AMHomeDirMechanism (vi will say "E486: Pattern not found: AMHomeDirMechanism"). Depending on the version, there will be 3 or 4 occurrences.
Then:
:wq {return} (This saves the file).
(NOTE: You may see "E138 Can't write ciminfo file $HOME/.viminfo!". If so, please hit the return key, then continue.)
exit {return}
This last line allows the boot to continue, and you should then be able to log in andINSTALL ADmitMac v6.
I did this and it did not work. Redoing this several times over, I noticed that the issue is that Drive is "Read-only". Changing permissions is above my "pay-grade" Any help will be appreciated it. I do not want to wipe out my hard drive and restart anew.Addendum: I read on a post here (http://forums.macrumors.com/showthread.php?t=420169) about removing some kext files in order to trick OSX into thinking that there were no FireWire ports.
I followed the instructions and removed from /System/Library/Extensions/ the following files:
IOFireWireSerialBusProtocolTransport.kext
IOFireWireAVC.kext
IOFireWireFamily.kext
IOFireWireIP.kext
IOFireWireSBP2.kext
I restarted and BAM...Snow Leopard booted crazy fast and the mouse and keyboard worked instantly.
The System Profiler says "No FireWire ports were found."
So this tells me that the FW port is probably the culprit and is messing up the installation.
So how do I hack the Mountain Lion installer and tell it to ignore the FW port, which is obviously quite dead? Or is there something I can do to the Base system that is similar? -
Two days I ago I installed 10.6.8 through Live Update. But, since then, I can't open Snow Leopard! Everytime I got the grey page and the request to reboot turning the Macbook off and then on. I could use Safe Mode, used Utility to repair all the processes and deleted any cache but nothing, tried a procedure of renaming the kernel found on the net and now I can't even open the Safe Mode. I don't even have here my Snow Leopard dvd! What should I do? Called the customer service twice but not that great help. Can I try to use another Snow Leopard dvd (i.e. from a friend of mine)? Should I format the partition and reinstall it? I'm really angry about this, got this Macbook since less than one year and it crashes after an autoupdate, probably forcing me to 700 km x 2 trip to get that dvd (and of course those of any other app I got?!)? Grrr.
... tried a procedure of renaming the kernel found on the net ...
If you've been doing things like that, you probably destroyed your system. You need the installation disc that came with the machine. Another one won't work, unless it's for the same model.
I'm really angry about this, got this Macbook since less than one year and it crashes after an autoupdate ...
It failed to boot because of incompatible third-party system modifications that you installed. We know that, because it started in safe mode. Then, instead of removing the modifications, which would have solved your problem, you did something that immobilized the machine completely. You should not have updated the OS without having an installation disc available, and you shouldn't be using a computer at all without backups. Apple can't protect you from the consequences of making bad choices. -
OS X Snow Leopard Update Software not displaying new updates
Hello Guys,
Sorry in advance for any spelling or grammar errors, English is not my native language, and I am only 14 as well.
So my problem is, Is that I recently lost my HDD due to a laptop fall and I have replaced it with a SSD. But the problems didn't arise until I reinstalled iLife '11. I use iLife A LOT, Mainly GarageBand for important music production,
Now, Since iLife doesn't come with most of the instruments, I used ASU (Apple Software Update) And it said no updates, so I went into GarageBand, and tapped update from there, and I got the same thing. So I later went into Airport Utility, It said I needed a update, it took me to software update, and I got the same "No new updates" message.
Not sure if it helps, probably makes matters worse, but in System Settings > Software Updates > Installed Software, there is "iLife Support" and 'iLife '11"
The computer I am on:
MacBook Pro Early 2006 15-inch
Mac OS X 10.6.8 Snow Leopard
1.83GHz Intel Core Duo
2GB RAM
Radeon X1600M
128GB Sandisk SSDTry installing the 10.6.8 Combo update which contains all the latest updates for that OS. Be aware that there appears to be no further support for Snow Leopard.

Problem with Snow Leopard and LED Cinema Display + MacBook pro
I just upgraded to Snow Leopard. When I work on my MacBook Pro everything works fine. But when I use through the LED Cinema Display then the machine hangs on several programs, like iTunes, Time Machine, even Finder. Before the upgrade everything worked fine. Anyone having the same problem?
I've had similar problems when using my cinema display. I am currently using it with my usb backup drive disconnected and , so far, have not had the problems. Here's hoping, although it is not a good permanent solution, it means I do not have Time Machine running or access to my other backup files. I suspect that it may be a problem (as reported by others on this forum) with SL mounting a sleeping drive. Time will tell.
