I don't have an exact figure, but Leopard is a fair amount larger than Tiger, e.g. all of the executable files in Leopard are "universal", including both Intel and PowerPC code, whereas all the files they would be replacing in your Tiger system only contain PowerPC code. Leopard needs more memory than Tiger, so if you aren't increasing your installed RAM at the same time, you should expect a greater degree of virtual memory activity, and that means more disk space will be needed by swap files. > Here are some Tiger folder sizes which are perhaps relevant: > > /System : 2.2 GB > Applications/utilities that came with Tiger : 4.07 GB > /Developer : 1.53 GB > /Library : 10.64 GB From my Mac Mini running Leopard: /System: 4.5 GB /Applications: 4.6 GB (including a few added ones but nothing especially big) /Developer: 3.1 GB /Library: 9.1 GB > I guess /Library is not that relevant. It is relevant, though you could save a fair amount there by NOT installing all the printer drivers. > In the absence of anecdotal evidence (which I hope you can give me), would > it be fair to say that the extra disk space required for the upgrade would > be: > > (9 - 2.2 - 4.07 - 1.53) GB = 1.2 GB ? No. You will need about 9 GB free to do the install, and as long as you do an Upgrade install, the previous system will be replaced, leaving you with the Leopard files replacing the Tiger files. I'd expect you to end up losing something in the order of 4 GB of disk space after installing Leopard and more recent developer tools. I'd be getting worried if I only had about 5 GB free space on my startup volume. -- David Empson dempson(a)actrix.gen.nz

You decided to buy one of these iPads, you did realise you needed Leopard right? Tiger is long gone these days, people run it but the majority of users will be on Leopard or SL. It doesn't take much to google for people's experiences, you're needs are specific enough that we can't give you answers. What software are you running? What are you hoping to do with the system? I say this because of RAM use in Leopard. If you're doing an archive and install you're going to need space for the older system, at least for a short time. You've given us very little to really go on. Notes how he has me in his killfile though and probably won't read this, but it's the same for installing any OS, do your own judgement of what you need first. Personally, i'd leave tiger on there if it's working.

Clone your disk before you begin, Jan

Ah, thanks, I didn't know what was normal. So looking deeper into it: /Library/Application Support/ : 4.76 GB /Library/Audio/Apple Loops/Apple Loops for GarageBand/ : 1.09 GB /Library/Audio/Apple Loops/iLife Sound Effects/ : 1.39 GB /Library/Printers/ : 1.57 GB Large folders within Application Support: /Library/Application Support/Adobe/ : 643 MB /Library/Application Support/iDVD/Themes/ : 1.69 GB /Library/Application Support/Garageband/ : 1.92 GB Large folders within Adobe: /Library/Application Support/Adobe/AdobeHelpData/ : 110 MB /Library/Application Support/Adobe/Fonts/ : 127 MB /Library/Application Support/Adobe/PDFL/ : 78 MB /Library/Application Support/Adobe/Templates/ : 175 MB Can I safely get rid of any of those? I am thinking iDVD Themes are useless since this iBook only has a Combo (not Super) drive. I am thinking iLife Sound Effects are pointless? |
