This was driving me crazy for a while my i9 Macbook Pro 16 lagging on keyboard input. WTF? Two things fixed it 1 - Turning off automated graphics switching - then the MBP runs on the dedicated graphics card. No more lag! So it has something to do with video drivers. But, this was using crazy amounts of battery, and since I run on battery quite often, it was not a good solution for me. 2 - Reset SMC and NVRAM (PRAM). This seems to have fixed it. Now lag-free with automatic graphics switching back on (it's reset to auto anyway when resetting SMC)

I imagine these are 1GB+ in size - when I select download, it downloads at 1% of my internet speed, I measure 100KB/s. Normally I get 10MB/s. So that's 1% of my normal speed, and I guess that's why it would take a very long time, were I to wait. I always have iStat Pro running showing network activity in the menu bar. They must be hosted on a shoebox somewhere... If Apple could move these into one of its humongous data centers, that would be great.

But that does not allow me to publish apps in the app store? I have some free apps, that have a few hundred users but I don't make money from them and I am happy to provide them for free. I just don't know why I have to pay 99 USD / year for the privilege of offering free apps?! I let my program expire now users complain they can't share my app anymore, since it's no longer on the store.
