Useful macOS / iOS tricks

Was visiting a friend who was playing a video game on his iPhone, and wanted to share it with a larger group. My mind was blown when he plugged it in to his mac, opened QuickTime Player.app and chose File > New movie Recording, then clicked the arrow and chose his iPhone as the source. Result: full screen iOS screen shows up on his mac (with sound).

I know you can use SharePlay to share iOS to macOS but this requires the latest macOS, and runs over wifi - the Quicktime Player trick works with older macOS and has better performance since it’s over USB.

I could see how this could be useful for development and debugging.

Greg just posted a neat tip about using the Safari developer extras on a mac from an iOS source: macOS HTMLViewer Developer Extras - #3 by Greg_O

Got any other fun tips or hacks?

Recording your iPhone’s screen can also be done directly on the device:

Another one, I think this was mentioned by @Beatrix_Willius :sunglasses:
In macOS Monterey, you can get back the “proxy” icons for Finder Windows:

  • Go to System Preferences / Accessibility / Display, and click “Show Window Title Icons”:

I’m so much happier with the Finder now, I really missed those icons.

Thank you.

I see no difference (M1 MacBook Pro here).

Care to share another screen shot (before/after, same window) ?

But I loved Increase Contrast ! Thanks.

You can add keyboard shortcuts to any menu item of any app using the Shortcuts Tab of the Keyboard Preferences. This will also change the keyboard shortcut if it already has one.

In this example I added a keyboard shortcut for Documentation in Xojo. (I know you can also change or add menu item keyboard shortcuts for Xojo inside Xojo’s preferences).

If you’re like me and you want Finder windows to open in the exact same spot at the exact same size every time, there’s an app for that!

Hey JazzUp can simulate the sound of Cherry MX keyboards :smiley:.

In a Save dialog, if you drag a file from a Finder window into the dialog, it will set the dialog to that directory.

In an Open dialog, if if you drag a file from a Finder window into the dialog, it will set the dialog to that directory with that file selected.

In a Save dialog, if you click on an existing greyed-out file in the chosen directory, it will set the file to be saved to the same name, which then can be edited to make it slightly different.

In Finder, you can hold the Option key and right-click a file to show a menu that allows copying the full path.

After:

With this setting off, you can see the proxy icon, but you have to mouse over the filename and wait a half second. I find the wait very annoying.

Combine this feature with Mail.app, Flags and Smart Mailboxes and you can set up a miniature organizing system. If you look at the Flagged mailbox, you will see different colored flags. You can rename these to create a “ToDo” system. Here’s mine:

I have set up keyboard shortcuts for each of these, which are now muscle-memory. So I can easily look at each incoming email and decide : Junk? Delete? Keep? DoNow? DoSoon?.. with a single keypress.

You can switch showing hidden files in Finder by pressing Command-Shift-. (dot).

Thank you.

In the Open / Save Dialog, you can rename the files, put them into Trash… with a right-click (maybe other things, but I do not used them).

Useful when you realize you’ve made a mistake when exporting a file (wrong type) and avoid a duplicate / going to the folder.

I saw a macOS beta where the "drop an item’ into a dialog resulted to a move to there, just like in Windows. This was removed in the next beta.

Right-click in the window’s name allows to navigate in that Item folder hierarchy. Nice for opening the current project’s folder in Xojo’s IDE (and not only).

Here’s one someone at Xojo didn’t know:
Holding the option key when opening a file in Finder will close the window “behind you”.

Apparently it also prevents Xojo from loading the UI state :roll_eyes:

I suspect that’s intentional. Because the UIState is embedded in binary projects if it ever became corrupted, holding Option down will skip the uistate data. That existed long before apple decided that Option should close the previous window.

Mac OS has been doing this since System 7 that I can recall. You can even try it out on the web here https://system7.app

I think (Option Key depressed at Xojo launch) ask for the License…

I found this:

but I was unable to get it in English. It is about renaminf files in the Finder.

And you can get the other help pages from there…
