fixed : how many 4K screens can my M1/M2/M3/M4 Mac handle simultaneously ?

Question :
I have an M3 MacBook that I would like to use with 2 external 4K monitors for my work setup, so I bought an extra 4K monitor, but when I tried to connect it to my MacBook, it didn’t work… What is wrong ?

How many displays can I connect to my M3 MacBook simultaneously ?


Answer :
There are hardware limitations to how many additional screens you can connect to a Silicon (M1/M2/M3/M4) Mac, and they are not the same for the basic M-version, the Pro-version and the Max-version. Actually, it’s quite confusing, because there’s also variation in what you can connect using either Thunderbolt or HDMI. Please find the number of external screens you can connect in the tables below [ warning ! the below may contain typos, do doublecheck on the official Apple website ] :

4K-resolutionover Thunderbolt onlyover Thunderbolt + HDMI
M1+1+1
M1 Pro+3+3
M1 Max+3+4

M2 Pro+2+2
M2 Max+3+4

M3 Pro+2+2 (but HDMI max. 4K)
M3 Max+3+4 (but HDMI max. 4K)
M4+2+2 (but HDMI max. 4K)

so… generally, all M1/M2/M3/M4 Macs can support at least one external 4K (or even 6K) screen, but if you want connect multiple external screens to your MacBook, you are probably goning to need a multi-monitor-hub, like the BenQ beCreatus DP1310 docking station.

The BenQ beCreatus DP1310 docking station will enable every silicon (M1/M2/M3/M4) MacBook to connect over USB-C to up to 3 external 4K screens (2 over HDMI and the 3rd over DP/DisplayPort).

The regular price of the DP1310 Dock is ca. €300, so check out below if you can get a better price on Amazon [we get a tiny fee if you buy anything using these links, but you will not be paying anything extra] :

fixed : delete multiple old mails at once in Mail.app on iPhone or iPad

Question :
On my Mac, in the Mail.app, I’ve always been fond of the option to select multiple eMails (mostly junk-mail) and delete them at once… but on my iPhone I have to delete each mail one-by-one (swipe left, click More, scroll down, click Delete Message) …that’s no problem if it’s only 5 eMails, but when it’s 10 or 20 eMails that I want to delete, it takes a lot of time and a lot of swiping…
Now a friend adviced me to sart using the Gmail.app to do this… and Gmail.app has this as a standard feature, and Mail.app doesn’t (as far as I know) …but I love using Mail.app and prefer to keep using Apple’s own stuff…

Isn’t there any way to do this in Mail.app ?


Answer :
YES, there is !
Okay – it’s slightly more complicated than in the Gmail.app for some unknown reason… but the option is there – to use it, do this :

in iOS / on iPhone :
– open Mail.app
– if you’re not already in the mailbox that you want to delete the eMails from, open the proper mailbox in the Mailboxes list window
– in the window where all eMails are listed, click Edit (top-right)
– now all eMails will slide slightly to the right and at the left, a round checkbox will apear in front of each eMail
– then, check all eMails that you want to delete (or move)
– when all are selected, click Move (bottom-centre)
– from the popup, select Move Message
– then, on the next screen click on Bin (or Trash) to delete all selected eMails
– the screen will automatically close and go back to the previous screen (your selected mailbox)

in iPadOS / on iPad :
– open Mail.app
– make sure you are in the right mailbox, if not, click the menu icon (top-left) and select the desired mailbox from the list that appears on the left, and click on the menu icon (top-left) again to close the list of mailboxes that had appeared on the left
– in the window of your desired mailbox, the list of eMails will be visible on the left and the preview of the selected eMail will be in the middle and right
– then click on Edit (top-right-in-the-left-column), above the list of eMails
– now all eMails will slide slightly to the right and at the left of them, a round checkbox will appear in front of each eMail
– then, check all eMails that you want to delete (or move)
– when all are selected, click Move (bottom-centre-in the left-column)
– from the popup, select Move Message
– then, in the list that appears on the left, click on Bin (or Trash) to delete all selected eMails
– the slide-in menu will automatically close and you will be back in the regular screen of the active mailbox

Note : both on iPhone and iPad, you can also use this method to move multiple eMails to the junk-mailbox or archive them to any desired mailbox

That’s it !

enjoy 😉
