I have just re-made the Catalina installer, with the updated OS. It could not install from it, like it could not copy. Then I have tried to reinstall Mojave, it worked pretty cleary last year the exact pen drive. It failed as well, saying something like: not package found, contact the system administrator. I was able to boot from USB pen drive Linux and install Windows from DVD. But no macOS from the pen drive, even from what worked fine before. I have reseted the BIOS several times, no succes. The first sign of something wrong was this: When I first tried to boot Catalina, it said something about BIOS (BIOS, not UEFI) reset and enter setup. I hapenned several times on my attempts. If something screwed in my hardware? The USB ports? The BIOS perhaps?
I purchased two of these Sipolar 10 port USB 3.0 hubs with the thought I'd be able to plug in 20 iPads to do software restores simultaneously, but I only can get 12 to be recognized at any one time. Both hubs function properly with 10 iPads plugged in to each at once, but as soon as I connect both hubs I get a max of 12 iPads recognized by the OS. We're using Apple Configurator 2 to restore iPads, and I have a separate older/slower 32 port USB 2.0 charge/sync hub that works fine with all devices plugged in.
I'm using a 2014 Mac Mini 7,1 running 10.15.3. I've tested the hubs with a few difference Macs and OS's and have had the same issue. From what I can tell these hubs use a RealTek USB chipset, but no drivers are offered by Realtek for them.
I attempted to daisy chain them (not ideal) and still have the same issue. Has anybody run in to a similar issue using identical USB hubs connected to individual ports on a Mac?
Hello everyone, I've an Acer Aspire E5-574 running Mojave at last update, everything is fine, except by the laggy mouse, as the attached, when the system needs the graphic card (Intel HD 520) it's generates a lag.

I have a dual-boot system with both Win10 and MacOS on separate drives. MacOS on an SSD while Windows is on a standard laptop HD. At first it was working fine and I haven't thought much of it but recently MacOS started acting weird. The first thing I noticed was that Clover somehow "forgot" my primary boot drive. This wasn't a huge issue though, as it was booting just fine once I hit enter on the drive selected. I updated Windows 10 to a newer build, however, I did all of this with the SSD drive unplugged just to be sure. Now Windows is working properly while MacOS is having some quite frustrating errors which make it impossible for me to work...
Anyway, the problems are the following:
- random reboots
- apps freeze or won't start just "bounce"
- internet not working(eventhough every other device connects just fine)
- system is laggy overall
I have tried emptying NVRAM int Terminal but I only got a message saying 'Error clearing firmware variables'. I've been searching for solutions on the web for the issue at hand but struggled to find one... I would really appreciate some help.
I attached my config.plist down below. If more information is required, please let me know.
