I have received my first mac from a designer friend who passed away recently. He had been having problems with crashing in Lion. His friend upgraded to Mountain Lion before his mac pro laptop, mid 2010, was sent to me. It has many problems and crashes

After sorting the material of my friends on the drive and creating a new user, I realized that the system was unusable with 30 or 40 crashes a day. I am a photoshop user and my friend had installed cs2 and upgraded to cs5. Actually everything was crashing and he had had the problems in Lion and they did not go away in Mountain Lion.
So my sense is the next best step is to uninstall and reinstall the operating system....but I'm entirely new to Mac though I quite good at problem solving on PC.  I have been messing around trying to get Mac up for over a week now so am learning quickly but feel uncertain about the steps in installation and don't want to mess things further.
I have found this
https://discussions.apple.com/docs/DOC-3351
which seems useful.
I'm backing everything now to a usb drive, I have one copy in timemachine, but I need a clean install so I'm backing things manually as it's not so complicated my being a new user.
I have the original discs of Snow Leopard and a dmg file of Mountain Lion that were installed on this computer.
I hope I can find my friends Adobe id and password.....he does have a list of passwords, how can I check if they are correct.
Do I need to install Snow leopard from the original disks first and then update and then upgrade to Mountain Lion?
He upgraded first to Lion but I can't find that program to install, do I need it to get to Mountain Lion?
I don't have boot disks, does that matter?
What can I do about CS5 in a restore? I don't mind loosing other programs so much as this one.....I haven't seen the upgrades and only have CS2. What happens to all your programs...I guess they are just lost?
I haven't used mail, so I'm not worried about that.
Hope I can get some support with the process, any support will be valued that is at all related. Thank you

I am looking through this material, it's great. I'm wondering though, does command r work in #8 if my original disks where Snow Leopard?
Yes, when the operating system was upgraded to 10.7 then to 10.8, it 10.6 was replaced so those 10.6 disks are only good now for completely erasing the entire drive and reverting the machine back to 10.6
10.7 and 10.8 has a Recovery HD partiton on the boot drive.
https://support.apple.com/kb/HT4718
I have a mountain lion dmg file that was used to upgrade from Lion, would double clicking on this equal the same thing as reinstalling mountain lion over itself?
I wouldn't use this, as Apple is now changing things, so you need to reinstall 10.8 via the Recovery HD
I would prefer to keep CS5 photoshop
Not going to happen, if it's working now good for you. But according to Roaring Apps it's not working for 10.8. and it needs to be upgraded to CS6
If you revert the machine to 10.6 or 10.7, your going to erase CS5 and everything else.
Doing #20 would be a bit beyond me and I don't know another mac user so that I can work from their mac.
Why do you need another Mac users machine?
Print out the instructions.
Here is some more about secure erasing for a new owner
How do I securely delete data from the machine?
Installing OS X 10.8 again
https://support.apple.com/kb/HT4718
Does the reinstall have to go from Snow Leopard which was the base install, to lion then to mountain lion,
No, you erase and install 10.8
When Apple upgrades 10.6 to 10.7 then to 10.8, it's a complete operating system replacement, it's called a upgrade because it's still OS X but leaves all your files and most programs intact, none of the older operating system version remains.
Just like if you would upgrade Vista to Windows 7, or Windows 7 to Windows 7 Pro.
Can I install the mountain lion upgrade over a freshly installed Snow Leopard?
Yes, but it requires erasing the entire drive (including 10.8 Recovery HD) from the 10.6 disks, then installing 10.6, then Software Updating to 10.6.8, then buying 10.8 from the AppStore, then downloading it and installing it, then the machine will be 10.8
Or you can use the Recovery HD and just erase the Macintosh HD parittion then reinstall 10.8 that way for free.
How to reinstall just OS X or erase/install OS X
https://support.apple.com/kb/HT4718
See what is confusing you is there is a hidden Recovery HD partition on the boot drive, it can do all the things like a OS X install disk can do, erase the Macintosh HD partiton (where OS X, programs and files are) and install a new copy of OSX from Apple's servers so it reboots to a brand new machine again (no Cs5 though)
Instead of a boot disk, there is a two bootable partitions on the boot drive, one is Recovery HD and the other is Macintosh HD which boots into OS X.
SO your command r booting the operating system in Recovery HD to erase the other partition and reinstall OS X into from Apple's servers, got it.? 
Your going to need your AppleID and password to reinstall OS X 10.8, all part of the new world order.

    I currently have Lion, when I upgrade to Mountain Lion, all my apps, music, videos and other files will be erased?

    Lion dropped application support for PowerPC. An OS may drop or change what to use to open a file, not the file.
    Of course CCC is what many have used for 10 yrs now and it is or will be $20 like SuperDuper - commercial.
    Always use something like those in addition to or instead of TimeMachine.

  • Will Photoshop CS6 work with Snow Leopard or must I upgrade to Mountain Lion on the Mac Book Pro?

    I will be purchasing PhotoShop CS6 & installing on my Mac Book Pro. Adobe tells me that I should upgrade to Mountain Lion from Snow Leopard in order for it to work best. Any thoughts on this? Thank you, Paul

    You can use it on Snow Leopard without any problem. However, Apple updates graphic drivers and more things, so it could run better on Mountain Lion, but as I said, if you don't want to upgrade, keep on Snow Leopard because it will run properly.
    Probably, Adobe is referring to the fact that Photoshop could be working in 32-bit because the kernel on Snow Leopard starts into 32-bit by default, and Mountain Lion is a 64-bit operating system. In this case, you will see an improvement

  • My mac book pro (2.66Ghz Intel core i7 4Gb ram) crashes every time I open iPhoto, browse photos or videos from Finder and work with slides, this started after I upgraded to mountain lion, what can I do??

    I updated my OS to mountain lion and since then my mac book pro is virtually useless, seeng pictures, videos, using graphics applications and Iphoto is impossible, the screen goes black, and the system restarts.
    This even happens sometimes at login, the login screen appears then the computer crashes and restarts, sometimes more than once, yesterday it even happened 6 times in a row before I was actually able to enter the password and log in.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac. 
    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. 
    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands. 
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
    Launch the Terminal application in any of the following ways: 
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) 
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. 
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid. 
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Triple-click the line of text below to select it:
    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' 
    Copy (command-C) the selected text to the Clipboard. Then click anywhere in the Terminal window and paste (command-V). Post the lines of output (if any) that appear below what you just entered. You can do that by copy-and-paste as well. Omit the final line ending in “$”. No typing is involved in this step.
    Step 2 
    Repeat with this line:
    sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}' 
    This time, you'll be prompted for your login password, which you do have to type. It won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning. 
    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
    Step 3
    launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}' 
    Step 4
    ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null  
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
    Step 5
    osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null 
    Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

One person I got was in germany I believe the other in Ireland. one went on vacation the other took over and now no emails at all on the status of my account thats been locked for over a month with no resolution in site. Isnt this a publicly traded company? Does anybody know how to get a hold of the board or someone above the service providers Im dealing with or a phone number? Emails are great but there no resolution from a person that can hide behind a computer screen.

  • Trouble Booting up when upgrade to 8GB ram on the Macbook Pro 13 Mid-2010 edition

    I have the right specs(two )Size: 4 GB Type: DDR3 Speed: 1067 MHz and it freeze when booting. but when I take one out and put one 4 GB and a 2 GB Ram, it boots and works fine at 6GB, I even change to a different more expensive brand ram and its the same issue, works at 6GB and not 8GB, Can someone help me.

    First off make sure, again, that you have the right memory -- 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM. If you do, swap out the the two modules. Place the 2G stick where the 4G was and put the 4G where the 2G was. Check your system RAM. If you do not have 6G then the slot where the 4G stick is is bad. If you have 6G, then swap out the two 4G sticks. If you now do not have 6G then the second 4G stick is bad. If you get 6G then we will try something else.

    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. 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.

  • I am using Leopard but need  Mountain Lion for the Mac App Store.  How do I get Snow Leopard to be able to upgrade to Mountain Lion?

    I am currently using Leopard but need Snow Leopard to be able to get Mountain Lion. I can see this is no longer available from Apple.  How would I get it so I could then get Mountain Lion. I want the Logic 9 Mac App Store App as I don't want to have to buy the whole Logc 9 from Studio 8.
    Some help would be much appreciated.
    Thanks
    Adam
