Im not sure if this is a all around thing, but "Time Machine" on my Studio f**ks my shiz up, and looking thru certain blogs I noticed a trend of people mentioning time-machine as doing this or that. All of which my issues seemed to be, ended up deleting Time Machine or well stopped it lol and never had any issues. Thats just bc you mentioned using it etc. But I have 2 external Toshiba's (4tb ea) that work great with the machine and a just in case seagate(2tb) all of which never had any issues.
-Toshiba CANVIO Advance Plus - Portable External Hard Drive USB 3.0 4TB - Here's the main ones!
-Seagate 2tb, was only 70 bucks and is one of the higher rated ones, Toshiba's only $100 ea
-I have the satechi base for my studio and to be honest it sucks. I could've went on amazon on got a knock off that did the same **** for 1/4 the cost. My drives constantly crashed being plugged into it. So I gave up and got a docking hub. But if you get these "accessories" just make sure you look close to their output ratings. I really didnt care that much as it took me a year to do anything about it lol But I kept getting pissed off about why my damn refresh rate wouldnt come close to the monitor(240/60). Kept reading that HDMI was the best cable choice and blah blah blah. I use display port to HDMI, instantly doubled the rate to 120. Then I lowered the res from 5120 and got my 240. But bc it's a 49" I went back to 5120. But upon reading little more into this issue(oh I even have a $200 usb-c thunderbolt cable) APPLE regulated which **** can get you that 8k res and 120 refresh if your monitor allows it. And its much more complex then I thought like just ****ing make them all do it fi you voice it to begin with. Bc you never hear them say, "oh btw you cant get this refresh rate if you do this. You must only do this." Heck no, they just say "can have up to 4 screen at blah blah blah or 2 screens at 8k" But yeah the satechi was mainly bc I wanted more USB-c for monitors when I have two used up for charging cords lol So yeah unless they revamped the crap out of that thing since beginning of year when I bought it. Get a high rated knock off at amazon or go with J5create docking station(again check the output ratings as most wont shell out over 60 hz except the $300 ones lol)
