smb big sur

I just updated it. After update the system to Big Sur, my mac began to slown down. I changed to undo the system but didn't work. MacBook Air(13.3', Early 2015) 1,6 GHz Intel Core i5 8 GB 1600 MHz LPDDR3 Intel Graphics 6000 1536 MB

I have a 2019 16” MacBook Pro and tried to update Catalina OS to Big Sur using update from preferences. I was connected to WiFi and everything looked normal with no errors on install. I saw the Big Sur desktop graphic but when the computer rebooted it reverted back to Catalina, now the latest version. Has anyone else seen this?

Anyone encountering an issue with Big Sur and the terminal failing to present a shell some reasonably short time after boot? Initially works no problems, after a while new Terminal windows open fine but the shell never loads and you're left looking at a cursor.

Has anyone had success installing exiftool under Big Sur (beta 2 is what I'm trying.) I can run the installer (which isn't signed so right click/open works) but the installer kicks me out saying that it's from an unknown developer. Is there a similar way to override that check on a package installer?

hi guys, I have Mac OS big sur beta 3 but trying to update to beta 4 but it is not allowing me to do so. What do I need to do to make this happen? When going onto update panel, it is saying update not found, the requested version of Mac OS is not available. Can anyone help?

sudo yarn dev Error: EROFS: read-only file system, mkdir '/logs' sudo mount -uw / mount_apfs: volume could not be mounted: Permission denied mount: / failed with 66 In previous cases of Catalina, you could start it, but you couldn't update it to big Sur How can I solve it

Hi, I upgraded my iMac OS from Catalina to Big Sur and Xcode to 12.2. My machine is very slow now and it's hard to open an Xcode project. All the junks were cleaned but the issue is not yet resolved. Please help me on this. Below I have mentioned my iMac configurations. iMac Retina 4K, 2017 Processor : 3.4 GHz Quad-Core Intel Core i5 Ram : 8 GB 2400 MHz DDR4 Storage : 1 TB Fusion Drive ( 463 GB available )

I am having trouble building a C library on Big Sur that previously worked on older versions of OSX. It relies on the PAGE_SIZE and PAGE_MASK macros, which previously were resolved by importing sys/vm_param.h. I'm not sure what the newer version of these macros are

Hello, we are currently investigating how to migrate our VFS kext (Kernel extension for a virtual file system) to macOS Big Sur. See related question - https://developer.apple.com/forums/thread/659502 As suggested, we plan to replace the deprecated kernel socket API with KEXT Controls. Now we noticed that the callback function (configured in ctl_register) to receive the data sent by the client (from user space) uses a memory buffer (mbuf): typedef errno_t (*ctl_send_func)(kern_ctl_ref kctlref, u_int32_t unit, void *unitinfo, mbuf_t m, int flags); However, according to the source code documentation, memory buffers are deprecated as well. Does this mean: Memory buffers won't work on Big Sur as well? Is there a way to avoid using memory buffers when using KEXT Controls? Thanks and regards Michael

Printer failed with update from Catalina to Big Sur. Removed printer/scanner Canon MG3060 from system, installed 'recommended' driver updates. Added printer back. Scanner functions perfectly, printer just 'hangs' telling me it is 'printing' but it does not. WiFi connection is fine, or of course the scanner wouldn't work. Frustrated beyond belief.

I have written a macOS app that uses the iTunesLibrary framework. The app utilizes the media item's persistentID as provided by the iTunesLibrary framework to manage the settings for the track within my app. I develop this app on an iMac (late 2015) using Xcode 12.4. I then distribute the app to my MacBook Air (2020 M1). I use Rsync to synchronize any music files from the Music Library that have been modified (lyrics/cover art, etc.), including the Music/Music/Music Library.musiclibrary database. The need for the persistentID of the media item to remain consistent from one machine to the other is paramount for the app to work. Otherwise, the app is broken. This is why I am Rsyncing the library database. I did not have an issue with this on macOS Big Sur 11.1 and earlier. The persistentID was being preserved on both machines and the software worked perfectly. However, for some reason now the persistentID is not being persistent across machines. It is like the Music database on the Macbook Air

Using ASWebAuthenticationSession and ASPresentationAnchor for OAuth has been working as expected but after updating to Big Sur the authentication flow is now opening two Safari windows. This occurs only when Safari is completely shutdown, when an instance is running a single window will be displayed as expected. Microsoft has an example which is having the same issue. https://github.com/Azure-Samples/ms-identity-macOS-swift-objc Has anyone else come across this with Big Sur?

After updating OS to Big Sur, My 2015 Macbook Pro doesn't search my external hard drive at all.

I have a MacBook pro 2017 and I am trying to update to macOS Big Sur that came out today, but it keeps getting stuck at 251.7 MB of 12.18 GB - About 2 days remaining. I have tried restarting, shutting down, and nothings seems to work. Anybody else having this issue?
