late 2012 Mini Me Firewire works great with macOS Sierra and PTHD 12.5.2
No video lag.

Late 2013 retina macbook pro with 1 HDX card and 12.5.2. Also no lag! So far so good!

Today I thought I go from El Crap back to Yosemite, since the GUI-lag (metering delay above 1 sec.) became unbearable with PT HD 12.5.2 in a bigger session, so basically I had to mix by ear only and forget all the metering...

Well, today I thought I do a test-upgrade to OS Sierra 10.12 before formatting my drive prior the Yosemite downgrade anyway.

SURPRISE!!!

All nasty problems gone with OS 10.12!!!!

Works like a charm with PT HD 12.5.2 and Logic Pro X 10.2.4, incl. the Core Audio with a 2.8GHz. Xeon Mac Pro (mid 2010 model).

I had no crash so far after intensive testing and all my metering, PT/Logic mixer windows as well as individual plugins are back to normal speed/usability!

Oh my... there's really a curse on this El Crap product from Apple - totally unusable. As a plus El Crap brought me back to network write speeds (file-transfer to a server disk) of below 2Mbit/s because El Crap somehow downgraded the SMB-connection protocol. Now with El Sierra I'm back to 100 Mbit/s+. I also don't have to shut down my machine by holding the power button for 2 seconds anymore. Are the El Crap pizzawheel dudes already jobless and fired?

All is excellent on Sierra over here. 2012 Macbook Pro. Protools 12.4 and Logic Pro 10.2.4 just smooth.
