M1 Mac Studio Finder hangs and crashes accessing Synology NAS

Issue

Synology DS916+

Finder on M1 Max Mac Studio 2022 hangs and crashes when performing certain file operations on Synology DiskStation 916+ NAS shares. Users can browse and open files on the NAS normally. However, when trying to save a new file from certain applications, the file is saved with no issues, but when trying to open, or just preview the new file, Finder becomes unresponsive for about a minute and then crashes. After Finder is re-opened everything is working fine again.

The issue doesn't affect older Macs with Intel processors.

Mac Mini M2 Pro with three Apple Studio Displays

Mac Mini and Studio Display

A user purchased Mac Mini M2 Pro (2023) with 3 Apple Studio 27'' 5K Displays. An Apple store happily sold him everything ensuring that it will "just work". Unfortunately, this wasn't the case. Although Mac Mini M2 Pro does support 3 displays, Apple tech specs page says the following:

Up to three displays: Two displays with up to 6K resolution at 60Hz over Thunderbolt and one display with up to 4K resolution at 60Hz over HDMI.

This seemed acceptable to the user and he purchased HDMI to Thunderbolt 4 / USB-C 4K cable to connect the third screen.

Remap Home and End key behaviour on a Mac

MX Keys

The following terminal script can be used to map Home and End keys on macOS so they work in the same way as they do in Windows and Linux: Home - beginning of the line, End - end of the line, Shift + Home - select text between cursor and beginning of the line, etc.

mkdir -p $HOME/Library/KeyBindings

echo '{

/* Remap Home / End keys to be correct */

"\UF729" = "moveToBeginningOfLine:"; /* Home */

"\UF72B" = "moveToEndOfLine:"; /* End */

"$\UF729" = "moveToBeginningOfLineAndModifySelection:"; /* Shift + Home */

"$\UF72B" = "moveToEndOfLineAndModifySelection:"; /* Shift + End */

"^\UF729" = "moveToBeginningOfDocument:"; /* Ctrl + Home */

"^\UF72B" = "moveToEndOfDocument:"; /* Ctrl + End */

"$^\UF729" = "moveToBeginningOfDocumentAndModifySelection:"; /* Shift + Ctrl + Home */

"$^\UF72B" = "moveToEndOfDocumentAndModifySelection:"; /* Shift + Ctrl + End */

}' > $HOME/Library/KeyBindings/DefaultKeyBinding.dict
