Your talking about 5 or 6 six different models of Macintosh and each year they may change the locations on most of them so you would have to either look in the help menu on your computer or go to Apples support site and download the manual from there.
A CD/DVD disc: It will depend what is on the disc. If there are files (Text, Video, Audio etc.) that the Mac can read then you can open them on the Mac. A hard disc: It will depend how the disc is formatted. Some will work. Some will be read only. Some will need reformatting to a Mac friendly format with Disk Utility.
Reformatting a hard disc will wipe the contents from the hard disc. You will need to backup the contents of the hard disc onto an external disc before reformatting and then copy the contents back to return it to the newly reformatted disc.
Windows is installed in a separate section of the hard disc and will not affect your existing data. As with any major changes to a hard disc it is advisable to have a back up copy of your hard disc on an external disc before starting the installation.
Restart and hold the C key until the Mac has found and started to boot from the disc. This will be longer than booting from a hard disc but should not be more than a minute or thereabouts.
The System folder is installed as part of the operating system at the top level of the hard disc. If you have more than one hard disc attached to the Mac hold down the Option (alt) key when the Mac starts up - this will open the Start Up Manager which enables you to switch the start up to another disc with a system folder. If you only have the one disc and the Mac is not finding the System folder you will need to reinstall the operating system from the installation discs.
Either the hard disc is damaged or the installation of Mac OS X is damaged. Either way boot from the Mac OS X installation DVD. Insert the disc restart the computer and hold down the C key while it starts up. Once you have the desk top loaded select Disk Utility from the menu and run repair/first aid to try and fix the hard disc. If the hard disc is not too badly damaged you will need to reinstall Mac OS X. If you do not have back ups of the contents of your hard disc you will need to try and salvage what you can. Performing an Archive and Install will save your stuff if there is enough space on the hard disc.
The Mac's iPhoto application will use whatever disc space is needed that is available, either on the internal hard disc or an external disc, depending on the size of the content in the photo library. There is no specific limit in gigabytes.
If a Mac computer is not accepting a disc, check the disc for surface scratches. Superficial scratches can compromise the disc and result in errors. You will also want to be sure that the disc is compatible with Mac computers.
You need the Mac Sims 2 game, and then when you put into your computer, a little sims 2 disc will pop up. click on it. Then drag the Sims 2 app to your hard drive, and it will begin to install. Be sure you have the MAC disc or it will not work!
Yes. Just make sure its connected when you're using parallels. when you install an OS with parallels edit its installation location to the location in the external hard disc.
If it is the Mac version of Spore and the Mac has an Intel processor (1.7GHz Core 2 Duo or higher) then the disc will work. If it is a Windows disc then it will not work unless the Mac is running Windows.
You can try inserting the Mac OS X installation disc and restarting the computer while holding down the C key. This will boot the computer from the installation disc allowing you to check if the hard disc is damaged with the Disk Utility available from the Desktop menus that load. If not a hard drive problem it may just be a corrupted Mac OS X file that will require reinstalling the Mac OS to fix.
