Will be interesting to see what Apple does about this in their next software update. I can’t imagine many people will be happy if the next software update forcibly disables hyper threading.
(For those who aren’t familiar with Apple devices, Apple don’t expose settings like this to a user, which are usually available in the BIOS on a PC)
Will the loss of HT have apparent consequences on most Intel-based Apple hardware? Very few of them are servers under constant multithreaded load, throughput-oriented. I suppose almost all Macbooks and most Mac Pros will not visibly slow down.
I would expect disabling HT on dual-core systems to have a noticeable performance impact on the desktop.
