I upgraded from snow leopard to mavericks only to find that my backup files of all my CS3 indesign, illustrator, photoshop wo't run, how do I uninstall mavericks and get my old system back. I retired from graphics a few years back but still have old clients I do work for and maintain files for. Would not have upgraded if I had known of the incompatability.

You did not due any due dilligence to investigate if your legacy apps would run, you should upgrade your apps. However if you feel you have to downgrade back to SL then click

How do I uninstall Safari and reinstall it again it's not working right and I've already wiped my computer clean to start over

Reinstalling Safari won't solve your problem, whatever it is. I suggest you start a new thread with a different title and a description of the actual problem, rather than your conclusion about how it should be solved.

Losing all mail. and watching them disappear in front of my eyes and could nothing about it
also when accessing cloud the screen just rolls in when accessing mail, like loading and loading and loading for 1 to 2 minuets.
I did not up grade my Mac Book Pro, and is working fine,
Just my iMac, its act kile avid card and it only happens access iCloud mail.
so I want to and need to go back to Loin

You can't unless you have a current backup of your old Lion system because the first thing you must do is erase the drive. It 's possible to use Target Disk Mode between your iMac and the MBP in order to clone the MBP to the iMac. However, that will still erase everything on the iMac's drive.
Or you could see about getting Yosemite to work correctly. If you have IMAP mail, then your mail should be intact.
Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Download and install the 10.10.1 update.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
5. Reinstall Yosemite from Scratch:
Download and install the 10.10.1 update.
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

Free Upgrade to Mavericks and not Mountain Lion?

I noticed I have a free upgrade to Mavericks. However, the application I'm using that prompted the search for the upgrade doesn't support Mavericks, I need Mountain Lion and I can't find a free upgrade to it anywhere. My question is; Why do I have a free upgrade to Mavericks and NOT Mountain Lion?
Thanks much!

Yeah I noticed it's there for purchase, pretty inexpensive as well $20. But I was just curious as to why the newer version is free and I can't find Mt. Lion for free, and that's the one I need. Maybe I'm not looking in the right place or it's just unavailable?

How do you uninstall i06 and reinstall i05 on an iPhone 4S?

There is no going back. You cannot downgrade to 5.

How long does it take to reinstall Mountain Lion on a new hard drive?

Due to performance/corruption issues, I erased my MacBook pro's hard drive. Now, I'm attempting to reinstall Mountain Lion (then do the upgrade to Mavericks). However, after about 5 hours of it doing the reinstall and downloading files (I have it connected to a network cable), I went to bed.
At some point during the night, the process seems to have timed out. Evidently, I will need to start from the beginning of the installation process.
My Questions:
How long should I take?
Is there a way I can prevent the MacBook from going into sleep mode so I can leave it unattended?
Since I've worked in corporate IT, I'm more than familiar with the Windows reinstall process and generally know what's going on and how long portions of an installation should take. Is there a way I can have the installation tell me what's going on?
Any other tips/tricks or general information?
Thank you for any assistance.

Wish I had your DSL speed. iTunes suggests I have about 7 1/2 hours still to go! Just glad it is giving it it's best shot.
Thanks for your reply.

How to uninstall maverick back to mountain lion?

I have instaled maverick but have found that it does not support some programs so wish to revert back to mountin lion. Is this possible and if it is can you give me a very basic explenation of how to do so.
Many thanks

Another option too for those (kind of like me) who never did the time machine.
I just restored my computer back to Mountain Lion, and she's working perfect again, as I knew she would. E-mail popping into mailbox instantly as it should and did before the update, printer working fast as it was before update, no more freezing or glitches of any kind thankfully and finally. Here is the link that is through the Apple site to direct you on how to put your system back and get rid of Maverick's, that is assuming that is what you would like to do and also includes link for those wanting to try fixing the issue if that is your preference (most of this info is for those with mountain lion and some with the previousverisoin of OS X lion).
If you want to keep Maverick's here is a good post on the apple discussion board to help you out:
https://discussions.apple.com/docs/DOC-6161
If you just want to totally get rid of it and put back what you had before, this is the short version of how to do so:
https://discussions.apple.com/docs/DOC-3353
NOTE: This particular link has a lot of info on what to do for different situations, it is a bit lengthy, yet still very helpful.

OS X: About OS X Recovery (also from apple support directly and includes some instructions just the same as previous links above):

Just in case you aren't sure what it will all look like as you are doing things, this is a link to show you a few pics of what you will see as you as you are going through the process, it can be helpful for those who aren't sure what they are doing or how to do things at all:

I hope this helps someone, it was amazing for me and my system is working perfect again like it was, battery life is way better went from like 3 hours to like 5 (not on full charge by the way, after it sat for a while doing the online update which took a while so that's saying something alone, huge improvement). I plan to wait a while before attempting to reinstall Maverick's, long enough for them to fix the bugs.

InDesign CS3 crashes when I export a PDF. I have updated it to 5.0.4 but it still crashed. I bought it as part of the Design Premium pack. How do I uninstall InDesignCS3 and reinstall the original software?

Hi, the title says it all
I've been trying to find out on the Adobe site how to uninstall CS3 Design Premium and then reinstall the original software in the hope that this will eliminate the crashing problem, which only started yesterday.
You're help will be very much appreciated.

Run the cleaner tool and reinstall.
Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
Just be aware that none of this will matter if you are using a newer version of e.g. Acrobat that by ways of updates may introduce/ have introduced an incompatible version of one of the PDF libraries commonly shared and used by all Adobe programs. you have to tread lightly and be careful...

How do I uninstall iPhoto and reinstall from the APP Store? I already own it, but it will not open now.

I have the latest version of iPhoto installed, but it will not open now. An earlier error message prompted me to update to the latest version, which I have. How cna I uninstall and reinstall this APP that I aleady own?
Thanks - David

Fixing that does not require reinstalling the iPhoto Application - it requires correct library issues
What exactly happens? What version of iPhoto do you have installed (in teh finder select it in the Applications folder and get info)?
If it iPhoto '11 version 9.5.1 then Back up your iPhoto library, Depress and hold the option (alt) and command keys and launch iPhoto - rebuild your iPhoto library database
