With the strong increase in hackers targeting Office 365 tenants, it may be useful to see who has Global Administrator access in your tenant. This can be done either via the Office 365 Portal but also through Powershell.
Note: be sure to install the required Powershell cmdlets before attempting this.
Connect to your Office 365 tenant:
To retrieve a list of users with the Global Administrator role, run this:
Get-MsolRoleMember -RoleObjectId $(Get-MsolRole -RoleName "Company Administrator").ObjectId | Select DisplayName,EmailAddress
You can append Export-Csv to export the list to a CSV-file.
By default, macOS'es Quick Look functionality caches previews of all files, even those found on file shares or encrypted file systems. This may not be what you want. Fortunately, you can disable Quick Look caching.
Open Terminal and type in these commands:
qlmanage -r disablecache qlmanage -r cache rm -rf $TMPDIR/../C/com.apple.QuickLook.thumbnailcache
If you want to set the Dock size in macOS to a specific value, you can use the Terminal to do so:
defaults write com.apple.dock tilesize -int 32; killall Dock
This will set the icon size to 32px, and then restart Dock. To get the current value of the Dock size:
defaults read com.apple.dock tilesize
