I'm gonna jump in as I have similar issues with Yosemite.
My two old white MacBooks run perfect with Snow leopard, but my 2011 17" i7 Macbook Pro is a dead slug with yosimite installed.
Tried the start with C held down, also with option held down. All it does is beeps at me three times, then again three times.....
I want to remove yosimite and install Snow leopard from dvd as yosimite runs worse than a Windows OS.
Can it be done, what do I need to do please?
Examples of faults, even with a 1tb solid state drive and 16 gig of ram, it is incredibly slow. Took four hours to install Logic 8 last night, I still have to reinstall logic 9 upgrade. On the White MacBooks I got both 8 and 9 installed in under an hour and a half all up.
Beeping on startup means failed RAM.
Slowness is usually caused by incompatible third-party system modifications.

I installed a game and when i start mozilla i am unable to start with the my home web page how can i fix

i installed a game and when i start mozilla i am unable to start with the my home web page. i set my home page in options tools. when i open Mozilla it opens in another page that i do not want

Some add-on or other software included with the "game" you installed might have "hijacked" your Firefox home page. I take it you tried resetting your home page? Ref: [[How to set the home page]]

Open Activity Monitor. Select All Processes instead of My Processes at the top and then reorder everything by highest CPU usage. Take a screenshot and post the image here.

How to Uninstall Yosemite? System does not allow Erase the HD, nor does it allow re-install of original O/S Disc (10.6.7). I want Mavericks or even Lion Back.   Thanks.

How to Uninstall Yosemite? System does not allow Erase the HD, nor does it allow re-install of original O/S Disc (10.6.7). I want Mavericks or even Lion Back.   Thanks.

Start with reinstalling Snow Leopard:
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. 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.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. After you finish Setup Assistant will complete the installation after which
         you will be running a fresh install of OS X. You can now begin the update process
         by opening Software Update and installing all recommended updates to bring your
         installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1 Access the App Store to download Mountain Lion or Yosemite. Mavericks is no longer available since the release of Yosemite. If you purchased Mountain Lion from the App Store, then you can redownload it via your Purchases page in App Store. If not, then you will need to purchase it from Apple;
Purchase a redemption code at the Online Apple Store: OS X Mountain Lion. Mountain Lion is $19.99 plus tax. Use the code to redeem a download of Mountain Lion from the App Store. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

TS3742 I have an iMac 24" system. I just recently installed MAC OS X 10.7.4 (Lion) on my system. Since doing so, my system consistently hangs. Particularly when using iMovie and iPhoto.

I have an iMac 24" system. I just recently installed MAC OS X 10.7.4 (Lion) on my system. Since doing so, my system consistently hangs. Particularly when using iMovie and iPhoto. I have to power off my system to get it running again. Any suggestions on what I can do to address this situation.

I would first reset the SMC:
Shut down and unplug the Mac.
Keep the Mac unplugged for at least fifteen seconds.
Plug the Mac back in and do not turn it back on for at least five seconds.
Press the power button to turn the Mac back on.
Then I would reset the PRAM by rebooting the iMac while simultaneously holding the Command-Option-P-R keys until the machine restarts a second time.
Let us know if these procedures don't solve the problems.
Hope this helps

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 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

I recently installed an Airport Extreme 802.11N that I bought in May 2013. It replaced an Airport Extreme 802.11N that I bought in July 2007. My USB printer (Lexmark E350d) worked fine with the old Airport, but the printer won't work with the new one.

I recently installed an Airport Extreme 802.11N that I bought in May 2013. It replaced an Airport Extreme 802.11N that I bought in July 2007. My USB printer (Lexmark E350d) worked fine with the old Airport, but I'm having trouble with the new one. When I try to print, I get a USB Waiting message on the printer, and when I force a page to print by pressing Go on the printer, I get a page that says ERROR: syntaxerror OFFENDING COMMAND: true. . . .cvt . . . fpgm . . . x . . .lglyf . . . <..J head . . . STACK: / [ -mark- /sfnts I’ve tried shutting down the printer and disconnecting it and the Airport, but that doesn’t help. I reset the settings on the printer. I upgraded the Airport firmware and removed, reinstalled, and upgraded the Lexmark printer driver. After I upgraded the firmware and printer driver, a few pages printed correctly, but then I got the same syntax error page as before. Any suggestions for getting the printer to work correctly?

Use a powered USB hub between the AE and the printer.. the usb port does sometimes have issues.
Try deleting the printer in the Mac and reinstall it.. the change in AE can represent effectively a change of printer.. it is important to make sure that is all up to date.
Beyond that.. USB printers.. ughhh! Consider for two toners you can go and buy a proper network printer.

Try the following steps:
1. Go to Microsoft website to fix install and Unistall problems. Click "Run now" from Fix it to remove all iTunes & related installer files:
http://support.microsoft.com/mats/Program_Install_and_Uninstall

Perhaps try downloading and saving a copy of the installer to a different PC. (If you're on a 32-bit Windows system, try to download on a different 32-bit Windows system.) Copy the iTunesSetup.exe installer to an external hard-drive, or a large-enough thumb drive or burn it to a CD-R. Carry the installer back to your PC, copy the installer to your hard drive. (Don't run the install from the ExHD, thumb or CD-R.) Start the install by doubleclicking the iTunesSetup.exe file.

Hi
how to download this and install?
There are no free DownLoads !
There are no legal DownLoads at all !
If there is no iDVD on Your Mac (and it's not on newer Macs as Apple discarded it) then You need a program that can do this.
Your Mac can burn CDs and DVDs - BUT DVD as Data-DVDs not as Video-DVDs - they need a program to be encoded and STRUCTURED as such.
• iDVD is part of the boxed version of iLife'11 and can only be bought outside Apple as on Amazon and e-bay
• DVD Studio pro - Part of FinalCut Studio Pro bundle - this to has expired and can only be bought second handed. (High price and tough learning Curve - but best ever done.)
• Roxio Toast™ - Not as elegant as iDVD - but has many other positive additions (I like it as 10-Pro incl BD-component) (now version 11)
• Burn - only free alternative I know of on internet. Very simple - Just for doing a plain Video-DVD
Burn http://www.digital-digest.com/software/Burn.html
only You can buy from Apple is
• FinalCut Pro-X which also can burn to DVD but without any nice themes.
AppleMan1958
You can also buy Compressor from Apple for $50 US. It will also create DVD and BluRay but without the nice themes.

HT1386 I have double and triples of photo's on my iPad. Not all my pics but most of them. I was told that I screwed up in synching with iTunes when I initally set up. How in the **** do I get rid of all the dups? I cannot delete them from my iPad. HELP ME

I have double and triples of photo's on my iPad. Not all my pics but most of them. I was told that I screwed up in synching with iTunes when I initally set up. How in the **** do I get rid of all the dups? I cannot delete them from my iPad. HELP ME!

If the shows are in fact still on the pad, they will be found in the videos app, not the music or I tunes app. Look there and see if they are still there.
If you don't see them there, go to the searchlight screen ( farthest left home page) and type in the name of one of the shows. If it is on the pad, hiding somewhere, this will find it.
If they are not there, they should not be using up space.
To get them back onto your pad, plug in and sync again. Make sure you transfer purchases first. Before you sync, take a look at the video tab in your I tunes, and check what you want and don't want synced.

You can paste it into any word processing program you have, evernotes as stated, the notes app, even into e-mail if you want.

I just upgraded to Lion and switched my web page from MobileMe to Godaddy. But since upgrading to Lion a video I placed on my web page no longer shows up. instead I get "plug-in failure". That didn't happen until the Lion Upgrade what do I do?

What's the format of your video? That will give you a hint as to what plugin is failing (or missing).
If you don't know, what's the URL of your site - it shouldn't take long for someone to work out the specifics.

Several times I've downloaded albums from iTunes to find that some of the tracks did not get fully downloaded so that the track with skip to the next one. Can someone tell me why this is happening and how I can fix it?

Several times I've downloaded an album from iTunes to find that not all of the tracks were fully downloaded so that some of the tracks will skip to the next one (instead of finishing the song). Can anyone tell me why this happens and how I can fix it?

If your country's iTunes Store allows you to redownload purchased tracks, I'd delete your current copies of the tracks and try redownloading fresh copies.
Otherwise, I'd report the problem to the iTunes Store.
Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
Find the items that are not playing properly. If you can't see "Report a Problem" next to the items, click the "Report a problem" button. Now click the "Report a Problem" links next to the items.
(Not entirely sure what happens after you click that link, but fingers crossed it should be relatively straightforward.)
