I have a 2020 13 inch MacBook Air and a 27 Inch Thunderbolt Display . I connect using the Apple adapter and everything worked fine until the Big Sur beta 2 update now the display will not turn on. I've tried everything including trying to set up using HDMI. Anyone have the same issue or have a fix?

Hello,I am using a MacBook Pro 2018 (more details: see screenshot) with the latest macOS Catalina Beta (19A536g) and a iPad 5th generation with the latest public beta (17A5565b).If I try to use Sidecar in the system preferences, I see "no devices" when trying to select a deviceAnyone else having the same problem? the problem exists since beta 3 I think.. before the update, sidecar was working nearly perfect.I already tried:- logging out and in again with the Apple ID- using a wired connection- checking both devices to be in the same network- Bluetooth and Wifi are enabled on both devices- Handoff is enabled- AirPlay is working with screen mirroring- Asking Google for helpIs this a bug or habe i forgotten something? Anyone else having this problem? Is there a known workaround?

I've got a WD My Passport 1TB SSD external drive. I also have 2 MacBook Airs, one mid 2013 and one less than a month old. I used the hard drive to transition from the old one to the new one. Both worked great.  I had the old one enrolled in the beta program so of course after moving to the new one it was too. They both upgraded to Big Sur one night. Long story short one of the programs I use regularly wasn't ready for Big Sur so I attempted to go back to Catalina. I plugged in the hard drive and it just sat there steadily flashing the light. No access in Finder.  I opened DiskUtility and there it was, greyed out with no access.. No mount, no first aid, nothing. So I opened Safari and did some looking. Meanwhile, I cleared out the old MacBook and loaded a new version of Catalina. Turns out, when I force quit fsckhfs, the drive is accessible and I can access it. While it passes all tests on WD's utility app, when I try to run first aid it fails after about 4 hours. Though I can still view and move files in finder, after the force quit of fsckhfs. If I try to renew from backup, I'm stuck because I can't force quit fsckhfs from that stage of boot yet I can't restore from backup after a full boot up. Should I attempt to erase the whole drive, reformat and start making new backups or is there a way to address the problem between the drive and fsckhfs? Interesting note, the drive worked perfectly with Catalina. After loading Big Sur it didn't work. After taking the older MacBook back from Big Sur to a fresh copy of Catalina, it didn't work anymore (unless I force quit fsck_hfs). FYI, the ext HD was connected to the old MacBook when it upgraded to Big Sur. The new one was never upgraded but the HD doesn't work when connected to the new one. Thanks to all for the assistance.

For the past 3-4 betas (currently beta 9), my Big Sur installation's Mac App Store has broken. iMovie and/or Final Cut never install; they download, with the progress 'roundel' going to its 3/4 position, but then there is no advancement. 'zsh', part of a process family tree that seems to include install-related components, spins at 100% CPU and nothing ever progresses further. One or two other apps have managed to update, but those two are both stuck. I've tried deleting and reinstalling the apps - well, now they won't install at all either, same problem. So, neither update nor install works. After a reboot, the prior broken state is restored. Battery life is awful, since one CPU core is constantly pegged at 100% CPU. Killing every process I can find related to the store or updates doesn't help as they soon respawn and the situation reoccurs. I've tried deleting the app store caches - no good. A few of the update-related files and folders are now no longer accessible even to sudo, and I don't want to go to the trouble of disabling SIPS etc. & safe mode unless I'm fairly sure it's doing any good, so haven't wiped those. I'd prefer to know what I'm doing rather than stampeding around deleting almost-random things with little more than guesswork. I was hoping that someone reading here knows how this stuff actually works and could perhaps direct me towards the magic file that needs deleting so the system doesn't just keep stupidly restoring the same crashed state. Ideally, I don't want to just reinstall the whole OS, since very likely, the situation will just repeat - after all, why wouldn't it? Happened once, happens again; the internet has plenty of articles about stuck store downloads going back years; that's why I'm looking for hopefully some real understanding of how the mechanism works, so that if the problem repeats it can be resolved. Even better, maybe I might be able to prevent it happening and/or formulate some kind of useful bug report that isn't just thrown in the bin because it basically says "This does not work" without any other particularly useful information. Thanks in advance for any ideas :-)

Since updating to the High Sierra beta, the media keys (skip backward, play/pause, skip forward) do not seem to be working with iTunes anymore. They do however work in Safari to control the playing and pausing of video content (e.g. YouTube).iTunes Version: 12.6.2.20macOS: 10.13 Beta (17A358a)Any ideas would be helpful!

Hello everyone! I have searched the web but have not found anyone with a similar issue. When Installing the Dev beta on my 2019 MacBook Pro it will finish installing at 12.88GB then it pulls up an error saying gatekeeper and installasistant.pkg failed or something along those lines. Anyone know a fix for this? thank you!

Can’t seem to figure out how to get rid of the music player on the lock screen. Even with no music playing it’s there. Anyone else seeing this? http://tinypic.com/r/10ghbgh/9

Hi, I installed and update the macOS Big Sur latest available beta and after installation is done, It is showing me battery service required warning in my battery icon, My mac is new and it's been hardly 5-6 months and used casually.

just wondering if anyone has been able to get the ps4 controller to pair with tvOS 13? Or is this something that will come in later betas?

tvOS14 has no option to choose an output source so No Airplay to homepods. Has the Option moved or been removed from this version? I see nothing about it in the release notes
