Can I uninstall 10.6.2 and go back to 10.5?

I just got a 2 year old MacBook Pro for my classroom to use with my Smart Board. I upgraded the MacBook to 10.6.2 and installed the latest version of NoteBook 10 software. When I could not get the software to install properly I contacted SmartTech and was told that their software does not work well with Snow Leopard and they don't know when they will have an upgrade. The same goes with the Texas Instruments software that I need to use. Can I downgrade back to Leopard where I think all of my software will work properly?

Welcome to Apple Discussions.
Read about downgrade installs
"You should not reinstall an earlier version of the same software over a later version. These "downgrade" installs may seem to work, but Apple does not test nor recommend downgrade installations in most cases. Some installers prevent downgrade installations. If you need to reinstall an earlier version of Mac OS X, erase your disk first or choose the erase option in the Mac OS X Installer. Be sure to reinstall any software updates after reinstalling the operating system."
EDIT: Also, you cannot install an OS that is older than the OS a Mac shipped with.

How can I uninstall Pages 5.2 and go back to Pages 4.3?

I am very frustrated using Pages 5.2. It is not as easy to use as 5.2 and causes me all sorts of problems - especially when highlighting text. How can I uninstall Pages 5.2 and go back to Pages 4.3 which was much easier to use?

Thanks. The new version of Pages and iMovie are useless to me. I need to delete the new version of Pages so my functional documents won't keep trying to "upgrade" to pages 5.2. It annoys me to no end. I hope they smarten up soon.
It seems that Apple is trying to turn its computer applications into iphone apps. They are eliminating essential features and functions that don't work on a 600 dollar pocket watch. It appears to be part of a misguided attempt to have universal cross-platform compatibility. Or they just want to get out of the computer business. I suspect that accountants are having too much influence on business models. There is a place for accountants. But giving too much control to bean counters can eliminate quality and cripple innovation, leading to the ultimate downfall of the corporation.

I tried to install Selenium IDE and got message "Selenium IDE Java formatter could not be installed because it is not compatible with Firefox 5.0". How can I uninstall Firefox 5.0 and roll back to a version that works with Selenium IDE? - 22 Jun-2011

I tried to install Selenium IDE and I am getting the message:
'''Selenium IDE Java formatter could not be installed because it is not compatible with Firefox 5.0''

You can turn off compatibility checking, but more and more of the Google Toolbar will not work. Google is no longer supporting the Google Toolbar so you should use the alternatives.
Hi Mark,

Can i uninstall iPhoto 9.4 and reinstall iphoto 9.3 from time machine and will my photos still be there?

can i uninstall iPhoto 9.4 and reinstall iphoto 9.3 from time machine and will my photos still be there?

Did you try to repair your library after the update to 9.4? Here's what you can try: make a temporary, backup copy of your library if you don't already have one (Control-click on the library and select Duplicate from the contextual menu) and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start with Option #3, followed by #4 and then #1 as needed.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
3 - 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.
4 - In the next window name the new library and select the location you want it to be placed.
5 - 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. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
If the above does'nt work and you want to go back to iPhoto 9.3 read this tutorial from iPhoto Library Manager's website: Fat Cat Software - iPhoto Library Manager Help - Downgrading a library to an earlier version of iPhoto

You can create a new profile as a test to check if your current profile is causing the problem.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
*http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox
You can try to disable hardware acceleration in Firefox.
*Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.

Can I uninstall FCE 4 from and Old iMac, and reinstall in a new iMac

I have and Old iMac G5, last year I bought FCE 4, and now, I'm changing to a new iMac Intel Core processor i5.
Can i uninstall the FCE 4 and Install it to my new iMac Intel core Processor i5?
Is really urgent.

legrma -
Yes, you can do this. Just uninstall FCE from your old G5 iMac; then install it on your new i5 iMac.
The license allows you to install FCE on 1 desktop Mac and 1 laptop Mac as long as you own both and do not use FCE on both at the same time. You can move it from Mac to Mac as long as you abide by the license terms.

How to uninstall 10.4.4 and go back to 10.4.3

Hi everyone:
Having font problems after 10.4.4 install (like others posted). What's the BEST method of uninstalling 10.4.4 and going back to 10.4.3. Can I just run the Mac Update 10.4.3 Combo Installer to return to the previous version?
Or is this going to cause even more problems?
Thanks,
PLC

Pop in your system disk (the cd your computer came with) and do an archive and install. It will keep all your files intact. Then you can do the 10.4.3 update combo.

Has Apple done anything to address the issue of Mountain Lion's inability to support Epson printers? I have a Stylus Photo RX620 that now is useless. I am not a computer geek so would rather not try to do an uninstall of Mt. Lion and go back to S.Leopard

Have you tried to open System Preferences, then Print & Scan and then try to Add + a printer?
I have an Epson RX580 and am using OS X 10.8.2 and it is working as a (Bonjour) printer. My Epson RX580 is plugged into my AirPort Extreme and I can print over my wireless network to the RX580. However, I do not see any Scan options with this setup.
Anyone know anything about getting the scanning portion of the RX580 to work over the network like the printing function does with my Airport Extreme? Or can I not "share" a scanner over the USB port on the Airport Extreme? I know, kind on topic/off topic - but I think it fits under OS questions better.
Thanks for your advice!

HT201364 how do I uninstall OS X Mavericks and revert back to OS mountain lion?

how do I uninstall OS X Mavericks and revert back to OS mountain lion?

You can't uninstall an OS X version. You would have to erase the drive and reinstall a prior OS version. That's why you should never upgrade without having a backup.
However, just about any router in the world should work with Mavericks, without the need of any DVD supplied software.

If you never backed up your phone to iTunes and never backed it up to iCloud all of your content is gone forever.

Rather than fiddle with the tar file, if it wasn't saved, or using Pacifist, simply DL and install the
Mac OS X 10.6.8 Update Combo v1.1 update. It'll wipe all Safari 5.1 components and install Safari 5.0.5.
