Can I upgrade to mac osx 10.8.5 on MacBook

Purchased MAC Book 2009 2.0 GHz, 2 GB 160 GB superdrive. Or do I need to purchase a new mac book?

You can upgrade from 10.6 straight to 10.9 with no problems as long as you have at least 4gb of RAM. Any program that runs under 10.6 should run under10.9.
Once you are at 10.6.8 Mavericks is still available from Apple. 100.9 Mavericks is a free download from the App Store.
Mavericks will require at least 2gb of RAM but really needs 4gb to run smoothly.
As for third party programs see this list for compatibility with 10.9 http://roaringapps.com/apps:table
Also Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Mavericks.
Before Mac switched to Intel processors in 2006 they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.

Can I upgrade from mac OSX 10.6.8 to 10.8?

Can I upgrade from mac OSX 10.6.8 to 10.8?

Same list as stedman1, but uses model numbers which is slightly more accurate.
Check that your computer is compatible with Mountain Lion.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
iMac (Mid 2007 or newer) model number 7,1 or higher
MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
MacBook Air (Late 2008 or newer) model number 2,1 or higher
Mac mini (Early 2009 or newer) model number 3,1 or higher
Mac Pro (Early 2008 or newer) model number 3,1 or higher
Xserve (Early 2009) model number 3,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better)
8 GB or more of available space
Check to make sure your applications are compatible. Application Compatibility
If you have applications that you want to use that aren’t compatible, you can retain Snow Leopard and create a new partition to install Mountain Lion on or you can run Snow Leopard server in a virtual mode.
If your computer isn't compatible, you might be able to upgrade to Lion. Computer Compatibility - Lion
If you can/do upgrade, I recommend you make a copy of the installer and move it out of your Applications folder. The installer self-destructs. The copy will keep you from having to download the installer again.

Can I upgrade my Mac OSX v. 10.5.8 to Snow Leopard (10.6)?

Get more information about your computer. Go to the Apple in the upper left corner of any window, then "About This Mac", then "More Info..." Copy and paste the information here, but omit the serial number and Hardware UUID (if present).
If it's an Intel iMac then yes.
Compare details of your computer with:

Can I upgrade a Mac OSX 10.6.8 to Mountain Lion?

I want to know if It is possible to upgrade my Mac OSX 10.6.8 to mountain Lion..

I'd suggest you hold off for at least version 10.8.2 to come out. The first two, 10.8.0 and 10.8.1, have proven problematic in terms of battery performance for a significant number of users (see the corresponding thread reaching Biblical proportions in this forum).

I just upgraded to Mac OSX Lion and can't attach documents to my hotmail. Can anyone help?

Hi there,
Over the last few days, this issue has been driving me up the wall too!
I downloaded Lion OS a few months ago, but it was only until a few days ago did i attempt to logon to Hotmail to check my account & send an email with an attachment.
Normally i use the MAC Mail app, which is synchronised to my hotmail account.
Anyway, I'm not sure whether the Lion OS is the root cause of the issue, however after much digging around on various forums - the issue for me was resolved by downloading the latest version of Microsoft Silverlight 5 (www.microsoft.com/silverlight). Its a free download....

You need to buy a Mac OS X 10.6 DVD and then run Software Update. No further OS upgrades are needed.

Your Mac is definitely one of the supported models? http://www.apple.com/uk/osx/specs/
If so, what happens when you try to download? Is it a case of nothing happens? If so, take a look at the suggestions under 'Stalled Download' in this link:
http://www.wired.com/gadgetlab/2013/10/mavericks-issues-and-fixes/#slideid-23477 1
Also, some usrs have found that logging out of the Mac App Store and then back in again and starting over has kick-started the download. It seems that the 5+gb download can take a long time to give any feedback as to what's happening.

If you have a Mid 2010 model: Computers that can be upgraded to use OS X Internet Recovery. If later then see below:
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
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.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
If you have an earlier model:
Clean Install of Snow Leopard
     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. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. 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.

HT3606 please help me to upgrade my mac osx 10.5.8 to mountain lion

please help me to upgrade my mac osx 10.5.8 to mountain lion. i am not able to do it.becoz i am not having app store.

Before you buy anything, first make sure your Mac is compatible.
Minimum specs for Snow Leopard. Mac OS X v10.6 Snow Leopard - Read the Technical Specifications
Note. You can no longer buy Snow Leopard from an Apple retail store, only as follows.
If you are in North America ... Last I read, you must call them (1-800-MY-APPLE). It is $29 plus tax for family pack and $19 plus tax for the individual use version.
In Europe or otherwise … call your National Apple Helpline … http://support.apple.com/kb/HE57
Once you have bought and upgraded you will need to apply the Combo updater for Snow Leopard. Mac OS X 10.6.8 Update Combo v1.1
For Mountain Lion the minimum specs are … technical specifications.
But if your computer meets those specs you can upgrade to Mountain Lion without any intermediate steps.

Photoshop CS4 will not open after system upgrade to Mac OSX Yosemite

I recently upgraded to Mac OSX Yosemite and unfortunately, my Photoshop CS4 will not open. The message says it requires Java SE6. I now have Java 7 update 71. I would appreciate suggestions from anyone who can help to resolve this problem. Thank you.

Thank you very much, Chris Cox. I followed the link in the error message to Apple's support page, downloaded and installed the Java for Mac OSX.
I can now open my PS CS4 again. What a relief!
Many thanks for your fast response and accurate advice.
Cheers!

Mac OS X 10.5 Leopard installation system requirements
http://support.apple.com/kb/TA24950
Leopard is no longer available at the Apple Store but may be available by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753).
If you can't obtain a retail install DVD from Apple, look on eBay or Google the installer part numbers to possibly find at an on-line store. Here's what to look for:
MB427Z/A Leopard 10.5.1 install DVD
MB576Z/A Leopard 10.5.4 install DVD
MB021Z/A Leopard 10.5.6 install DVD (single user)
MB022Z/A Leopard 10.5.6 install DVD (5-user family pack)

Mac OS X 10.5 Leopard Installation and Setup Guide
http://manuals.info.apple.com/en/leopard_install-setup.pdf
After you install the base 10.5, download & install the 10.5.8 combo update at http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update
The DVD should look like this
Caution - Leopard does not support classic mode. So, if you currently open OS 9 apps in classic mode, you won't be able to do this if you upgrade to Leopard.
