My early 2011 13" MBP currently has OS X 10.9.5 Mavericks installed. The machine has 16GB RAM and two 1TB SSDs. An ExpressCard adapter is connected to the Thunderbolt port to run a UAD Solo, and an RME Fireface 800 is connected to, of course, the FW800 port. An iConnect MIDI4+ is connected to one of the USB ports. Both SSDs are backed up (main drive fully bootable) using CarbonCopyCloner.
I am looking to make the jump to a later OS…considering 10.10 Yosemite or 10.11 El Capitan. I’m unsure as to sure whether 10.12 Sierra will impact performance…not even considering High Sierra 10.13, as my box might be too old and under-equipped to handle it.
Any recommendations, tips, success stories, horror stories, etc. would be most appreciated. TIA! )
