catalina 10.15.4

Installed some software and some updates then no OS now loads. The machine unknown to me has a bios password, so i cannot boot in to the fresh Catalina that was on the ssd. I have tried all i know to boot or trick the 2012 i5 macbook pro but the padlock icon comes on. NVRAM reset, recovery...

Hi. I just recently got a new 2020 MacBook Air, which is running Catalina. On my old 2011 MacBook I had an older version of BlueStacks that was able to play a game called Elves vs. Dwarves flawlessly. The old MacBook was running Sierra. I downloaded the most up to date version of...

Both external disks connected by Thunderbolt 3 and USB3.1 to my 19,1 iMac Catalina 10.15.4 have been made both readable and writable by me the owner. I used the Apple+I window to do this. It is strange that I CAN CHANGE the ICONS of my internal 2TB SSD & my Time Machine Thunderbolt connected 1TB...

I was browsing through some mp4 videos with preview (space bar + up/down) when my mac froze. So i restarted it with long power button press. When it restarted, I didn't have menu bar, my wallpaper was black and I couldn't click on anything. I went to safe mode and it was completely the same, no...

Hi all, I recently (against my better judgement) updated my early 2015 13" rMBP from OS X 10.11 El Capitan to macOS 10.15.4 Catalina. Since then, I have been struggling against complete system shutdowns. Irregularly, but often immediately after powering on, the whole system locks down and...

Hello fellow Mac fans, my new 16 inch macbook pro has been having a few problems ever since I updated my OS to catalina 10.15.4. 1) I've noticed that sometimes my laptop doesn't shut down when I try to turn it off forcing me to hold down the power button in order to turn it off. 2) the bigger...

Can anyone tell me what this is? I just installed python3 idk if this has anything to do with it. Thanks!

✅ Resolved: The 10.15.4 Supplemental Update resolved the problem. Since updating to 10.15.4 I can no longer use my iPad in Sidecar mode or over AirPlay, as the color profile rendering distorts as soon as the second display connects. Manually choosing different profiles shows momentary...

I have a late 2017 13" MBP. Today the trackpad and the keyboard stopped working at the same time. The only thing that works is the power button (and the touchbar). Nothing happened prior to the incident so I don't know why the hell they stopped working all of a sudden. But I've noticed one...

Since I updated to Catalina 10.15.4 I've been having problems with my video on Safari, especially while trying to watch Netflix. For example, while watching a video, randomly and occasionally the video will skip for a second. It only happens on Safari, not on Chrome. Any idea what it can be or...
