I've run XLD Universal Binary on everything from Power PC G4 through G5 to recent Intel minis, Macbooks, iMacs and Mac Pros without problem (IOW, every architecture and OS since Panther).
When it comes to ripping CDs accurately, XLD is among those that take such variables into consideration as 'read sample offset correction' (and 'write sample offset' for those that burn the occasional disc).
And, with a decode library backend, it has been format upgradeable since the beginning, without the sufferance of flakey third party plug-ins; never a flaky FLAC, or OMG this OGG sucks.
I use iTunes so the option to 'Add encoded files to iTunes if possible' (I like that description), even to a specific playlist, is ideal. Were I only ripping my own CDs I could just as easily rely on iTunes own in-built ripping, however, I do buy and sample the odd FLAC and appreciate verifiable bit perfect conversion to ALAC.
I also find the UI to be right on, straightforward and simple, almost perfectly in line with Apple's classic standards, with no faffing about necessary, but lots of optimization options for those who want/need them.
Frankly, I find it surprising that it is still Donationware.
P.S. To anyone experiencing constant crashing of any Mac application, I can only suggest forced termination of the XLD process (specifically MPlayerX) via Activity Monitor deletion of same (and all supporting files) followed by reinstallation of same or an earlier or later build/version.
