Small companies usually. It helps being somewhere that runs a cross platform stack like Java and/or targets Linux servers anyway. Once I'd been here a few months, they trusted me not to brick the laptop, they're fine with me installing Linux on a Mac if I say it works better for me and I can leave OS X on there as a dual boot. Big companies are usually less willing, either due to some OS specific software or policies that enforce some specific encryption/security/monitoring.
