Degraded Monitor Performance Post Snow Leopard Install

Hi.
I have noticed substantial degraded Monitor Performance since installing Snow Leopard. The Monitor is an NEC MultiSync 20WMGX2. The picture is "washed out" looking. Any ideas what the problem might be? The Monitor Settings are as followngs:
Brightness 50.0%
Contrast 43.0%
Sharpness 50.0%
Advanced DV Mode is "on"
DV Mode is set for Text
The Graphics Card is the standard Mac Mini Intel GMA950 with 64MB of shared system memory.
Thanks for any suggestions on how to get the performance back for this monitor.
Mike

Are you aware that the default display gamma has been switched from 1.8 to the default value of 2.2? If you want to build a 1.8 profile, then you still can. Some interpret the change as degradation.

IMovie Viewer issues Post Snow Leopard install

Hi,
I just fired up iMovie (09) after upgrading OS to Snow Leopard (newer iMac bought 4 months ago). I no longer see the project video in the viewer. The "raw" movies in Event Library play fine, but when trying to play the movie in the project library, I only get audio. If viewing in full screen mode, all is well. If i go back and press space bar from project Library, only audio.
All worked fin prior to the snow leopard upgrade. Anybody know what is happening and how I can preview my movies from the project library again?
Thx !
Glenn

Yes, we've been having quite a few issues since the upgrade, too. Now correlation does not equal causation, so I can't say for sure that Snow Leopard is the problem. All I know it that all this stuff started happening afterword.
Here is the thread in which I posted my issues, some of which are quite similar to the those of Jay_S:
http://discussions.apple.com/thread.jspa?threadID=2141045&tstart=15
Jay, the solution to your problem recommended by an Apple Expert seemed to fix things, so you might want to take a look. It's in the third paragraph.

Slow CS3 / system performance after Snow Leopard install

Since installing 10.6, I've noticed a systemwide slower performance; there's a slight hesitation after everything I do. Even something as simple as changing a filename causes a second or two of hesitation... then it lets me change the name.
This is especially noticeable in CS3 software; painting or editing in Photoshop is very difficult, because there's a second or two of hesitation before things occur. Even clicking menu items takes a second before the item opens.
Anyone else have this? So far, 10.6 (and yes, 10.6.1) have been a definite downgrade to my performance.

I have noticed no hesitation or slowdown, in fact startup and shutdown are noticeably faster, and system wide speed is same or better.
This is only relevant for photoshop, but ...

I have a copy of Windows 7, and I am trying to bring up Boot Camp on my MacBook with Snow Leopard. But my Snow Leopard install disk is too old for Windows 7, so attempted Boot Camp install of drivers fails.

I have a copy of Windows 7, and I am trying to bring up Boot Camp on my MacBook with Snow Leopard. But my Snow Leopard install disk is too old for Windows 7, so attempted Boot Camp install of drivers fails.
I have hand-installed the NVidia graphics driver, and I have keyboard, minimal trackpad, and hardwire to internet all working. So the WIndows machine is usable. But I am hurting for wi-fi, better trackpad, and whatever else is delivered by Boot Camp. I can't use any of the Boot Camp upgrades because I do not have XP or Vista.

While we all have MacBooks in this forum not all of us use Boot Camp. There's a Boot Camp Support Community where everybody uses Boot Camp. You should also post this question there.

Basic Snow Leopard install with special customization: setup assistant infinite loop problem.

Hi, all,
Based on this post: https://discussions.apple.com/thread/1395118?start=0&tstart=0, I'm assuming there's a problem with setup assistant running after a customization install reboot. But I could be wrong.
Here are the details:
MacBook Pro
Clean OS X Snow Leopard install (I was "told" by IT I had to wipe the disk and re-install OS X after backing up personal files).
Installed extras I need/want (in particular, XCode, though I went ahead with the other optional software as well).
Installed the IT supplied "Supplemental CompanyName Installation Disc" (also referred to as "CompanyName Supplemental Installation Disc" ), which is supposed to create a customized, IT supported, setup.
When the supplemental install is done, the system is rebooted.
There is then a "Welcome" screen (starscape, with almost endless bombardment of the word welcome in various languages), finally followed by:
a) select language; b) select keyboard; c) select timezone; d) Don't forget to register your Mac, with a "done" button.
Clicking the "done" button goes to a blank grey screen. and then loops back to redo the "Welcome/language/keyboard/done" sequence, ad nauseum (that is, infinitely repeated).
Per the above mentioned post, I have rebooted to the Install DVD and run disk utility, repairing permissions. No difference on reboot.
Boot to safe mode goes to the same setup assistant sequence, not a login screen.
Another Mac user here suggested checking for /var/db/.applesetupdone, since missing it, or if it's correupt, could cause this problem.
So I booted to single user and checked for this file. It is not there. On the off chance the file is a simple flag and the content doesn't matter,
I did fsck/remount and touch /var/db/.applesetupdone but this did not change anything either.
Presumably, the file must be present and must contain some data. If this is true, can it be created manually and put in place via single user mode?
Or are there other, better solutions someone could suggest?
Many thanks.
Bob

Ah, it seems I finally found something useful, at http://hintsforums.macworld.com/showthread.php?t=84825
One of the responders supplied the content of their .applesetupdone file.
I was able to get this onto my Mac, in /var/db, as .applesetupdone (just to be safe, I linked that name to .AppleSetupDone, the name as mentioned on the above site). Note that both names begin with a dot (hidden, in UNIX parlance).
On reboot I was presented with the CompanyName specific login screen. It took a little bit more mucking around with passwords, but I was eventually able to login without any problem.

Will Mac OS X Snow Leopard INSTALL on a IMAc g3 slot lOADER?

will Mac OS X Snow Leopard INSTALL on a IMAc g3 slot lOADER?

That's what we needed.
Officially your iMac--known as a "tray-loader" for its optical drive type--can go to Panther (10.3.X). Panther is quite better than Jaguar (10.2.8) that you now have. You probably need more RAM than 160MB for even Jaguar. I feel that 384MB is about min for that OS.
The big problem is that the early iMacs came with painfully small hard drives --4 to 6 G--and OSX need a lot of free space on the disk for efficient performance. It's hard to keep a Jaguar system under 2G with a few useful apps installed.
Bottom line: you'll spent money for a hard-to-find retail OS install disk, more RAM, and a bigger hard drive, and you'll still have a slow computer that will always struggle with modern web pages. If you want to upgrade and experiment as a hobby or learnign experience and you can afford the parts and time, by all means--go for it. However, if cost is an issue, throwing money at this unit is not cost-effective in terms of how much more yo ucan get from it.

My MACBOOK Pro turned out to be Snow Leopard, and later upgraded to LION. And update the EFI, I would like to replace the Snow Leopard, EFI can not boot, how do? How to use the Snow Leopard install disk to reduce EFI?

Do you mean some of your software does not work in Lion? Do you want to return to using Snow Leopard? If so, then do this:
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

Installing Mountain Lion from Snow Leopard, Install failed and HD write-locked

I recently downloaded the mountain lion installer from the App Store and I ran the installer. Stupid person as I am, I did not have any backups for my file and I naively assumed that an apple OS installer would be without flaws. Boy, was I wrong. I need every bytes of my data (or close to every bytes) but the installer failed.
Mid installation, the installer stopped and said that the installation failed and that I need to repair my disk. So I restarted the computer and I ran disk utilities (my start up disk was the OS installer and the installer allows me to run several programs, including terminal, disk utilities, and by the way, when I held option while starting up to see which start up disks I have, I only had the OS installer as the start up disk. Also, the installer allows me to run a program called "Startup Disk" when I click on the apple logo on the top left corner, but it doesn't allow me to startup my computer using Macintosh HD) and noticed that when I highlighted Macintosh HD, my "Repair Disk" button was grayed out. So first things first, I ran the "Verify Disk" button but after a minute or so, Disk Utilities said that verification failed and that Macintosh HD needs to be repaired. But the "repair disk" button is grayed out! So I went to the Mountain Lion installer again and ran it. Of course, it failed again so I restarted the computer.
So I tried to first back up all files in Macintosh HD to an external hard drive using Disk Utilities, and I used features such as "New Image" and "Restore" but they both ended up in "Input/Output error". I tried many methods with Disk Utilities but they resulted in errors.
After some research, I noticed that some people's computers worked after they reset their PRAM. So that's what I did. I held command+option+P+R when computer started up and I reset the PRAM. When the start up disk (which is the OS installer, not the normal operating system) loaded, I was greeted with choose languages option and then I was back in the Mountain Lion installer state. I again ran the installer again, hoping something would be different, but then it was different. But not in a good way. When I was told to choose where I would like to install Mountain Lion, I noticed that Macintosh HD was grayed out. Last time, I was at least able to run the installer but this time, Macintosh HD was grayed out. The installer said that my Macintosh HD was locked. After some research, I learned that apparently, the Mountain Lion installer write-locks Macintosh HD mid installation.
So now I am stuck and I am thinking of two things (plus some questions)
1. I am wondering if there is a way to unlock Macintosh HD. But even if I can unlock Macintosh HD, there is no guarantee that the installer will successfully install Mountain Lion, am I right?
a. so how can I un-write-lock Macintosh HD?
2. More realistically, I am thinking of borrowing someone else's macintosh computer and use it as the backup center. I have a firewire cable and a terrabyte external hard drive. So what I'm thinking is that I'll hook my computer in target mode to my friend's computer and I will also plug in my external hard drive to my friend's computer and then I can download and run Carbon Copy Cloner from my friend's computer to copy all data from my Macintosh HD to my external hard drive. And then I will erase my Macintosh HD, freshly install Mountain Lion onto it and then copy all data back from my external hard drive. But I am not sure about few things.
a. it looks like my Macintosh HD is write-locked. Can I still use Carbon Copy Cloner to copy all data from Macintosh HD (in target mode) to my external hard drive?
b. will my computer allow me to erase (or format) Macintosh HD?
c. will my erased/formatted Macintosh HD able to install + be installed Mountain Lion OS?
If you are here, then you have read my long long problem. Thank you very much and I would really really really appreciate your answers and opinions. Thanks

I'm not sure where you read that about the disk being "write-locked." That doesn't make much sense, given that the major task an installer like this must achieve is writing a whole bunch of files to the hard drive. I think your source was mistaken.
As to what happened, it sounds like your hard drive was badly corrupt to start with, or possibly was on the edge of failing and is now in the process of dying entirely. If you don't have backups of your data, that does not bode well for you, unfortunately. If you can manage to use target mode to copy your data, do that.
Once you're sure you've got all your data, you need to start up from your Snow Leopard install disk and repair the hard drive. (Since it sounds like the Mountain Lion installer didn't work, I wouldn't trust the recovery partition that Mountain Lion installs.) Or, even better, just erase the hard drive entirely and reinstall Snow Leopard. Then, once you're back up and running, with all your data back on the system and with Snow Leopard updated to the most recent version, try installing Mountain Lion again. If any of that fails again, the problem is likely to be a dying hard drive, and you'll need to replace it.

HP Photosmart C6300 printer/scanner not working after Snow Leopard install

HP Photosmart C6300 printer/scanner not working after Snow Leopard install
Reinstalling etc does not work - does anyone else have the same problem or a clue as to how to fix this?

Keith,
I got a C6280 and the scanner does not work anymore. I am for 6 days in contact with HP. The last printer driver install form the apple web site does not open the image of HewlettPackardPrinterDrivers.dmg because of an invalid checksum. The skipping of the validation gives and error in the install.

I want to install Yosemite onto an external hard drive, and keep Snow Leopard installed on the internal hard drive. I want to be able to boot from either system, depending upon circumstance (at least until Yosemite is stable). Is this possible?

iMac, Model Identifier iMac12,1 with 121.5" screen, 2.8 GHz Intel Core i7 processor, 8 GB 1333 MHz DDR3 memory, 1 TB internal hard drive, running Snow Leopard 10.6.8 from internal drive.
I want to install Yosemite onto a 1 TB external hard drive (OWC) , and keep Snow Leopard installed on the internal hard drive. I want to be able to boot from either system, depending upon circumstance (at least until Yosemite is stable). Is this possible?

It is possible. I'll let you read some articles that cover the setup:

Can I restore a time machine osx lion backup using snow leopard install DVD?

Hi.
I've been using osx lion but my hard drive died. Fortunately I have been making time machine backups. Since I downloaded lion from the app store I only have the snow leopard install disks.
I know there is an option to restore from a time machine backup using the snow leopard disk, but since the time machine backup is of a later operating system (lion) will that time machine restore work?
If it won't, can you recommend how to restore from my time machine backup?
Thanks.

Once the replacement hard drive is installed, boot from your original Snow Leopard Installation Disk. From there format the harddrive and install Snow Leopard and then download and install its Updates. Next, navigate to the Mac App Store and login using the Exact same Apple User ID that you did the first time you downloaded Lion. You will now be able to download and install the Lion OS for Free. Download and install the Lion Updates. Lastly, using Migration Assistant, migrate your Apps and Data from the Time Machine external hard drive to your internal Lion harddrive. This method should give you a very stable version of Lion on your internal harddrive complete with all your previous settings, Apps and Data.
Hope this helps

Attempting Disk repair with Snow Leopard install DVD. Prompted to restart several times

Hi,
I'm trying to do a disk repair with my MBP (2010, OS X snow leopard). I tried to enter Disk Utility with my Snow Leopard install DVD by pressing down "c" during startup but it gives me a grey screen in several languages prompting me to restart again. Restarted and I get the same screen. Can anyone help me?

You are getting a (kernel) panic crash booting from the installer dvd? Hmmm. That's doesn't sound good. Try resetting smc and pram.
If that doesn't fix it try to boot the Apple Hardware Test and check your machine -- assuming that will boot?
Also look inside if you get that panic crash and see if there are any diagnostic leds lit.
If this continues you might try disconnecting all unnecessary peripherals (usb, fw, extra drives).

Re-installing iPhoto '08 after "fresh" Snow Leopard install.

Sorry if I'm beating a dead horse here, but I keep seeing conflicting info on whether or not one can, or should, do a drag-drop of iPhoto from one volume to another. Here's my story:
I had an older version of iPhoto on my iMac. I bought a MacBook in late 2008, which came with Leopard and iPhoto 08 (7.1.5). I did a simple iPhoto drag/drop from the MacBook to the iMac, also running Leopard. Things have been working fine for 1.5 years now.
I just did a Snow Leopard install onto a clean drive and, because SL doesn't include iPhoto, I again did a drag/drop of that same iPhoto app, this time from an older drive to the new SL boot drive, which had never been loaded with an operating system of any kind.
Again, things seem to be working fine.
Do I have any reason to worry that I might run into problems with this odd iPhoto "installation" on a Snow Leopard System? Why have I read so often that simply dragging iPhoto from one disk to another is to be avoided?
Thanks.

Frankly, I'm astonished that it even launches. iPhoto nowadays relies on many support files for the various features integrating with the OS and other apps and usually requires installation from an installer disk. I personally would install from a disk.
Regards
TD

I used utilities to source my 10.6 snow leopard install disc to my main hardrive, and now when I turn on my computer the apple with the spinning wheel stays on the screen and stuck like that. How do I fix it Help please. I already tried all the commands

I used utilities to source my 10.6 snow leopard install disc to my main hardrive, and now when I turn on my computer the apple with the spinning wheel stays on the screen and stuck like that. How do I fix it Help please. I already tried all the commands such as Command R, Holding down the Option key, C and holding down shift at the start up but nothing happens.
initialy All I was trying to do was downgrade 10.7 to 10.6 .

You have to consider the possibility the hard drive may be dying. If your data isn't backed up, try one of the tools below:
https://discussions.apple.com/docs/DOC-1689
Once you are sure your data is backed up, we can examine other possibilities. In the meantime call AppleCare for your original installation DVDs. You may need them.
