Hello,
On windows, when you are holding an item (e.g. a speed coil), you are able to interact with ClickDetectors on parts by pressing the ctrl key, as you would if you weren’t holding that item.
There is supposed to be a similar functionality on mac using the command key, however this functionality is absent from the roblox player, but it works in studio. In the roblox player, pressing the command key messes up movement inputs by holding the last movement until you hit the input key again. It also doesn’t allow the player to interact with ClickDetectors on parts as you would in studio on mac, or on windows.
This bug has been around for quite a while now. This bug disadvantages mac players in combat games that require opening doors while holding a speed coil or the gun in safe mode.
