If you reformat the drive you'll erase all the present data on it. If it's a brand new drive, just format it for FAT32 and both -Win7 and OS X- can read it. As to the file size limit, there is none.

No reformatting necessary as the hard drive ships in FAT32 format, which is instantly compatible with a Mac. If there is /any/ chance that you will be hooking into a Mac and a PC at some point, I'd highly recommend leaving the formatting as is (of course you can wipe the drive and then reformat it in MSDOS format through Disk Utility). You cannot easily write to a Windows (i.e., NTFS) drive but you can read it on a Mac. Have no idea as to whether a Windows machine can read/write something that is Mac formatted, however.

My use of this drive has been exclusively on the Mac. However, I did not use any of the back-up software or formatting provided on the drive. It was necessary to use the Mac disk utility to reformat the drive. Then it worked with Apple's Time Machine.

Yes, it has two partitions - one for Win and one for Mac, so you don't have to format it. It will work on both.

Yes. The Mac version is (obviously) formatted to be fully compatible with all Macs. You can very easily format it to an exFAT file system (look for tutorials online) to make it work seamlessly with any modern Mac AND Windows computer.BTW, consider upgrading from Mountain Lion to the latest OS X Mavericks. It's easy and free.

Greetings: I installed on a Mac Pro (1,1) with Lion 10.7.5. It fried my computer. I would leave it alone, especially after I spoke with a Mac repair type in Oklahoma City. Sorry.

What I've read on the Internet, if you reformat it, you can. The programs that are on it are of no use to Mac user. You might check with the software co., itself:Customer SupportNTI Corporationhttp://www.NTICorp.comClick here for contact information or call (949)421-0720 from 9AM to 6PM Pacific Timeand see if they have anything for the Apple stuff, but I doubt, never hurt to try, though. Anyway, this drive comes already formatted for Windows NTFS. The included works great with Windows XP. It doesn't seem to agree with Windows 7 but you can back your Windows 7 with the software that is part of Windows 7, with no problem.Hopefully, I answered several questions.

It will work on a mac computer. Check the file system when you get it. If it is NTFS, yes you will have to reformat. If it is fat32 you can use it in the mac straight away. Either way, I would recommend you reformat it to exfat because fat32 has a much smaller file size limitation.

Fortunately no. I still use an older Mac and OS. There is a comaprison chart at Roaring Apps to see if any other things with Lion/Mountain Lion. Good Luck!

I have windows 7 and it works fine. The box says it is mac compatible up to 10.7 lion. I would think it would work for yours to seeing as os usually try to make them backwards compatible but I don't really have much knowledge with macs.

You should be able to use it on both Windows and Mac to read and write. You just have to reformat the drive for FAT32 rather than NTFS. I did this with my WD my passport ultra, works fine unless Toshiba has documentation that states you cannot format FAT32, but I doubt it.

Unfortunately, I can't answer this as I have no experience with Mac's. The instructions only discuss how to install with these versions of Windows: 98, ME, 2000 & XP. I happen to have Windows 7 as my OS, and it works just fine, however I don't know what OS Mac's use. If Windows, then you will probably be ok, if another, then I would not waste time or money, because returning the item does not look very easy. Wish I could help more!

Yes. Your Mac will ask how you want to format the drive. You choose the format that works best in your environment.

It completely depends on how you format the hard drive and from which computer you format it from (from Windows or Mac). You will have several options for formatting the drive in disk utility on a Mac, including MacOS extended (journaled) and MS-DOS file system (which will end up being FAT32). Windows AND Mac can read from FAT32 partitions, but *only* Mac can read from MacOS extended (which, if you are using the drive as a time machine, you need to format it as - note: unless you have a very specific application that needs it, choose the MacOS extended WITHOUT case sensitivity). To use the drive for both time machine and MS-Dos compatibility, just choose to make two partitions and choose one of each! You find this option in the pull down menu called "volume scheme". So, if you format from Mac and are not using the whole drive for Time Machine, make a second MS-DOS file system partition. That one will be readable by both. If you just want one that will transfer files between the two systems and don't use Time Machine, just make one that is MS-DOS file system. If instead you are formatting from Windows, choose ExFAT or FAT32 to make a cross-compatible drive. NTFS will be readable, but not natively write to it (you would need to procure another program that allows Mac to write to NTFS). Note that you won't be able to use Time Machine with either of these choices. Edit: If needed, you could also subsequently reformat the whole drive for windows usage, but you would lose all stored data. So be careful!
