MacBook HDMI connection problem after Snow Leopard Update

I recently upgraded my MacBook to Snow Leopard and discovered my HDMI set up no longer works after the upgrade. It has worked for the past two years with Leopard without any problems. Now when I plug in my HDMI the computer recognizes that the TV is there but only shows up black on the TV. Checked the display settings and is set on "Mirror" still. Everything is the same except the OS upgrade. Has anyone had this problem and found a way to fix it? Any suggestions?
Thank you.

Hi Guys
I've read through a lot of the forums on this subject and it seems the problem has been going on since pretty much the start of Snow Leopard being introduced.
One of the questions I've seen is: will buying a new battery solve the problem?, The entry from BeetleMegaFan on the below forum may offer some advice to this question, it would seem apparently not.
http://forums.cnet.com/7723-21565_102-357366.html
Another thing I tried is removing the com.apple.PowerManagement preference which at least seemed to allow the MacBook to see my battery long enough to take some screengrabs of the System Profiler (could be one of the random co-incidences).
Just to check/prove this is "potentially" a Snow Leopard problem I booted up from my original 10.5 system discs and guess what, no problems.
I also got a new one yesterday: Battery not charging, the joy continues but at least it knew there was a battery in there!
Would really appreciate an answer or advice on this one but I'm fast thinking there isn't a solution available at present.

First, click your Apple menu icon top left in your screen then click Software Update...
If the system is up to date, try reinstalling the AMDS...

Desktop problems after Snow Leopard Installation

After a successful installation of Snow Leopard I am having problems with my Desktop. No matter what Desktop graphic I choose, after 2-3 minutes the Desktop goes back to a plain blue background. Any idea what is causing this? and how to fix it?

Hmm,
I was not familiar with EarthDesk but now that I know about it - I conjecture that application runs in the background, right?
If it does run in the background - then that is the real base of the problem installing Snow Leopard. Others with (other) apps running in the background have experienced repeated run-then-eject-installer problems. One person reported that CarbonCopyCloner's scheduling app caused this specific problem.
Now, I understand that the desktop problem isn't the same as having the installer begin to run, then stop and eject the installer disk. My point is only that apps running in the background are apparently causing (now various) problems with the SL installer.
Glad to see that one more problem has been solved.

Problems with MacBook after Snow Leopard Update

I have an older macbook that I recently updated to snow leopard and since the update my fan is always running and my computer is slower in general. At times my computer starts having huge lag and all apps quit responding. This is incredibly frustrating and if anyone could help me fix this I would greatly appreciate it.
P.S. Since updating videos on youtube.com also will not play without lagging but movies on any other site are okay, even youtube videos embedded on other sites.

You might also try deleting the dynamic loader shared cache. This sometimes can lead to apps bogging down and delays all around.
The easiest way to do this is a Safe Boot this will delete dyld cache among other things.
Follow the link for more info or hold down the Shift key at restart, keep it down and power back on. Keep Shift down all the way to the desktop. This starts your Mac, more slowly, and ask for log-in.
Then restart as normal, which will take noticeably longer as cache files get rebuilt. See if this helps.

Flickering Blue Image in iMovie '09 after Snow Leopard update 10.6.2

Hello Everyone
I am having an issue with flickering blue images during transitions in iMovie '09, but only after installing Snow Leopard. I usually only have about 10-15GB of space to spare, as I only have an 80GB HD MacBook Pro Intel Core Duo. However, I have two 1TB G-Drives by G-Technologies. It was mentioned in another post that my HD space was the problem. It worked great in Leopard, so I'm not sure I agree that 10-15GB of HD space wouldn't be enough to do a 20 minute video using only pictures.
Once I updated to 10.6.2 this issue began. I am in need of a solid app, and I presumed iMovie was my best bet for the money. I recently downloaded a demo of PulpMotion, but I'm still playing around with it. Any help would be greatly appreciated, as Apple users are among some of the smartest and most creative people I know.
Thank you,

Hello Sauble,
I just got off of the phone with Dan, an Apple iLife '09 Tech Support Rep. Here is the advice he gave me, and so far it has worked!
*Close ALL Open Apps*
Go To - Home Folder (house)
Go To - Library
Go To - Caches
Drag "Caches" folder to the trash.
Empty Trash. (Not all of Caches will empty. Just press "Continue" until complete.)
Shut Down Computer.
Press Power button to start up your computer. Once you hear the Apple Chime - Hold Down The "Shift" key until you see 2 things (The Apple Logo, and The Spinning Wheel), Then Release the "Shift" key.
Once your computer is back up, You Are Now In Safe Mode - Empty Trash Again.
(Your Trash Should Be Completely Empty)
Restart Your Computer as normal
Once your computer is up, open iPhoto or iMovie and see if your photos or Projects still have the same issue with blue or green people. Hopefully, NOT. LOL!
This should fix the problem. Let me know how it goes and if you have any information you feel would be necessary for this subject.
I wish you well.

Mail wont open after snow leopard update

Mail refuses to open after update,when initated it flashes in the tray then disappears,has apple a fix for this problem?
Or admits it exists.
Thanks

Mac OS X v10.6: Mail.app won’t open, or "You can't use this version of Mail…" alert after installing Security Update 2012-004:
http://support.apple.com/kb/TS4424?viewlocale=en_US&locale=en_US
Fellow user Grant Bennet-Alder offers this solution:
Some users have reported this problem if the Mail Application has been moved out of the top-level /Applications folder, or duplicated in another location.
When the Security Update is done, the old version of Mail is disabled.
The solution has been to:
1) make certain Mail is in the /Applications folder
2) There is no other copy anywhere else.
3) Once steps 1 and 2 have been done, Manually download and re-apply the Security Update (2012-004) by hand.
Security Update 2012-004 (Snow Leopard)
If the Mail.app has been LOST, it can be re-installed by applying the 10.6.8 version 1.1 combo update. But this update is quite large and it is usually not necessary:

Aperture 2.1.4 update will not load after Snow Leopard update

Has any one found the fix for aperture 2.1.4 update not loading after the installation of Snow Leopard. I to am also getting the alert "aperture 2.0 or later is required to install the update". I installed my copy of aperture 2.1 using the installer with no problems so the program is in the correct location. I've seen the posts related to this problem and it does not seem a fix has been found.

Just ran into this myself. I did check to see if there was a preference to delete under ~/Library/Preferences and one is not created since 2.1 is never actually launched. 2.1 is sitting in the root of Applications and hasn't been renamed, but the 2.1.4 update just doesn't detect that it is there and just gives the alert "Aperture 2.0 or later is required to install this update."

Firefox loads gmail fine. I've do not have google gears installed and I've reset safari several times now. www.google.com wouldn't open at first, but after the rest it loaded. Gmail has not.
Thanks in Advance

After I installed Gears for Snow Leopard It worked fine.

Wiki problems after Snow Leopard Upgrade

Hi,
I upgraded an XServe running 10.5.(whatever the last version was) to Snow Leopard Server using a 10.6.3 retail disc.
At the end of the install I was given a message saying:
The following actions failed or were not attempted:
Setting locale
Upgrading Services
To be honest the server seems mostly ok - but I have a few problems with the Wiki and Blogs:
When I go to http://myserver/groups I get what looks like the old Leopard groups home page - but it looks like its missing a stylesheet somewhere (although there are no errors in the web debugger)
When I click a link to view a group I get a javascript popup with the error:
The versions of the server and UI don’t match. Try clicking Reload; if that doesn't work, please make sure both server components are up-to-date.
Client: 20100118.dw01
Server: WikiServerUI-201
I had hoped that a Software Update would sort it out but I've installed all the available updates and still have the problems above.
I'm guessing that the wiki/blog problems are related to the failed "Upgrading Services" message, so how do I go about running the upgrade manually?
Thanks,
Ash

Any advice out there? I've even taken bypassed my main Extreme base to plug the ethernet connection directly into the Mac desktop to do software updates that might have been missed by going through the Extreme and wifi. While it did install one security update, it didn't affect the Express units.
I'm wondering about firmware. I have checked over and over for software updates, and my system assures me that everything is up to date. However, I'm concerned that somehow I'm missing a firmware update. My Airport Utility tells me my Extreme is running on Version 5.7, and on the few times one of the Express units shows up, it shows as running Version 6.#.
Do I need to manually install a firmware update, and if so, how? I terrified that I will mess up the ONE wifi unit that is functioning.
Ironically, my Extreme base is the oldest in my batch-both of the Express units are newer than it.

Mac-Windows-Connection failes after Snow Leopard Installation

I am dealing with 4 PCs at home – an IMac, a MacBookPro, a Dell Dimension and a Dell Precision Workstation. Before I installed Snow Leopard I could connect easily from my Macs to my PC via “Connect with Server” and the “sudo pico /etc/hosts” hint to rename my Windows-PC to real names (e.g. Dimension and Precision). After the installation I am prompted in OS X to give my account name and password again! And, of course, I don’t work anymore (wrong user name or password error). Because I put those information in long ago, I am not quite sure if I am putting the wrong Name/Password info in or if something happened during the Snow Leopard installation. I was never quite sure if “Name” meant the name of my Windows account I want to log into, or my Mac user name or a combination of both or the Server /Name thing, e.g. Dimension\Name. Just for info: My Windows-PCs can still connect without a problem to both Macs.
Any help is appreciated what information exactly to put in that **** Name/Password box that appears if I want to connect to a Windows-PC from my Mac. Or what else could have happened during the Snow Leopard installation that cut of the former available ability to connect to my Windows-PC from OS X.

I was able to see the other Windows XP computer and begin to connect. I was then presented with a login screen. I tried using the usual user name and password - no luck. I then formatted the user name as as follows:
user name: computer name\user name
password: as normal
And it worked. Specifically in my case:
user: cwy-pln2152\administrator
password: planning
This is what worked for me your mileage may vary.

ISight not working after Snow Leopard update?

I just realized my iSight isnt working. I dont see it in System Profiler and I remeber prior to the Snow Leopard upgrade the iSight was working fine. This was three months ago, since the update i never had to use it until now. I tried resetting the SMC, I tried the command + option + p + r and still nothing.

• If you have not already done so, restart Mac and
    try again. If the iSight still does not work, continue.
• If Apple's http://support.apple.com/kb/HT2090
   suggestions do not help you, (are you certain that you
   used the correct "reset" procedure?), yours may be a
   hardware problem that will require a professional fix.
   Unless you have a current backup, make one now.
Then consider the final "Troubleshooting" suggestion:
"... contact Apple or an Apple-Authorized Service Provider for service."
• If I understand correctly, you are now using Snow Leopard.
   If you want to try one more thing on your own before
   seeking professional help. use Disk Utility to repair permissions.
   Then download and apply the latest Combo Update
   for your OS. The latest SL Combo Update at present is here:
     http://support.apple.com/kb/DL1399
• Repair permissions again immediately following the system restart
   that completes the Combo update.
Properly applying the Combo version of updates
can sometimes correct problems like yours.

Can't import audio files in FCP after snow leopard update

i've recently updated to snow leopard. and i'm running Final Cut Pro 6.0.6
i opened a .fcp project i created a long time ago. i tried to import a .aif file and final cut crashes. i converted the .aif file to a .mp3 file. tried to import it, and final cut crashed.
i then went and deleted the preference files for final cut pro, reopened final cut, tried importing both files again, it still crashes.
does anyone have a legitimate answer for why this is happening?

BenB wrote:
1st, FCP does not officially support MP3 audio files, so don't even use them. I'm running FCP 7 on Snow Leopard, no problems with audio files.
1- How are you encoding them? What software is creating these files?
2- Are you running on an external FW800 drive?
3- How much RAM are you running?
And as my final observation is, NEVER run Final Cut Pro 6 on Snow Leopard! Huge no-no! If you upgrade to Snow Leopard, only use FCS3. I've updated lots of systems for my students and clients, and I've seen lots of FCP6 on SL problems.
Message was edited by: BenB
I agree that you shouldn't use MP3 files with FCP, the manual tells you that somewhere If I recall properly, but it shouldn't cause Final Cut to crash, at least that has never been my experience, it has just caused a skipping problem, or not playing the complete song.
I don't really understand wht a FW800 drive or the amount of RAM have to do with it, it would sure be interesting to hear your comments on that.
However, in all due respect, to make the statement that one should NEVER run Final Cut Pro 6 on Snow Leopard seems pretty "out there" would you be so kind as to provide your rationale for such a drastic statement as that. Has there been anything official from Apple along those lines?

MacBook won't boot after Snow Leopard Updatel

I installed the 10.6.3 update today and after the "installation complete" message and subsequent restart, my computer would load the gray screen. That's where the normal boot up would end. It would then switch to the blue loading screen followed by the Nebula login screen. But then it would loop between those two screens every 20 seconds or so. Occasionally on the nebula screen the login box would appear but if I tried to type or click anything I'd get the dreaded spinning beachball of death followed by a flicker and a return to the blue screen. Is anyone else experiencing this? I've tried booting into safe mode which does nothing. I booted from the disc and "repaired" the disc with no luck. Is here any fix I can do without having to erase and reinstall snow leopard?

Try downloading the "conbo" update and running that. If that does not work, run your install DVD without erasing the drive. That should do an automatic A&I and get you going again.
