Who says you can’t have your cake and eat it? Go ahead and enjoy the new features Lion brings, while knowing that at a moment’s notice, you can create the right environment for your PowerPC apps to come back to life. Once this is up and running, a Snow Leopard environment with support for Rosetta will be created, and you’ll have an easy way to run PowerPC apps without having to reboot. This app guides you through the process well, allowing you to allocated hard drive space and even a specific amount of RAM. To do this, you’ll need an application that can create a virtual environment, such as VirtualBox ( ). If a dual boot setup isn’t your thing, consider, running SL virtually from within your Lion OS. Run PowerPC apps in a virtual environment The next time you need to run a PowerPC application, boot up in Snow Leopard and you’ll be good to go. This will take you to a screen allowing you to choose which OS you want to load – 10.6 or 10.7. When you next boot up your Mac, hold down the Option key when you press the Power button.
MAC OS ALTERNATIVE FOR POWER PC INSTALL
Do this by inserting the installation CD your Mac (pre-summer 2011) and choosing to install on the newly-made second partition. The first half contains OS X Lion, and it’s your task to install SL in the second half. Once this is done, hit ‘Apply’ – your disk is now partitioned. You can choose to partition the drive into two equal parts (default), or perhaps to make a smaller SL partition – just change the value in the ‘Size’ box. The graphic will now show a split in the hard drive. Click the ‘+’ icon underneath the graphic representation of the drive (showing how much space is used up).
Selecting your hard drive, choose ‘Partition’ from the toolbar. One solution to the PowerPC problem, then, is to partition your hard drive and install one OS in either partition. Run your Mac with dual bootĪlthough Lion doesn’t include Rosetta support, Snow Leopard runs it without a grumble.
However, there are ways of reintroducing Rosetta and breathing new life into your PowerPC apps. The theory behind this is that because the translation process makes these apps run slower, it’s best to get rid of them altogether and stick to Intel format. With Lion, Apple is getting rid of Rosetta, and so making it impossible for Macs to read the untranslated PowerPC code. The format needs to be translated before Macs can run these applications, and the translation is done using a process called Rosetta. PowerPC, though, is where the difficulties are found. Universal is similarly problem-free, as it includes both Intel and PowerPC support – the only problem being that this dual support increases the file size of these apps and eats up disk space. As you’d expect, the latter is fine, as all Macs these days run with Intel processors. Mac apps come in three different flavours: PowerPC, Universal and Intel.
Is it possible to claw back control over these apps on your new operating system? Yet this is a hard hit to take if you use Logic, Photoshop, Dreamweaver or any number of industry-standard applications in their current iterations.
MAC OS ALTERNATIVE FOR POWER PC PC
The company’s made no secret of the fact that with this release, they’re ditching support for applications in Power PC format. So, enticed by smooth gestures, full-screen apps and an iOS-like Launchpad, you’ve made the move to Apple’s latest big cat, Lion.
