Well that's. Just. Great. I bought a 64GB M4 Max MBP last month. I'm past the 14-day return window. I figured the M5 was near, but assumed M5 Max would come a bit later. Not sure where I came up with that.
This is always the gamble with buying a Mac. Either purchase right when the new is released, or be on the fence of your new becoming old a couple of weeks after purchase.
Not sure either since M5 base has been available for months now
M5 has been out since last year, no?
You can console yourself with the fact that your laptop, unlike one of the new ones if you'd bought that instead, can run macOS Sequoia (without "Liquid Glass") rather than Tahoe.
