10.4: How to rotate OS X's display 35 comments Create New Account
Click here to return to the '10.4: How to rotate OS X's display' hint

You can rotate Macbook display orientation on Mac OS 10.15 to capture more data at a glance from spreadsheets, or to have a better view of a game scenario. Some Macs come with hardware that doesn’t support this function. And in some others, you may need to use a more intricate technique to rotate the display on Mac OS 10.15. Pictureflect Photo Viewer is a folder-based image viewing app with minimalist feel designed to: - easily show your photos in fullscreen with a manual or timed slideshow - review your photos with a clean interface, fast load, and a range of zoom options - crop, resize and convert (individually or in bulk), rotate, apply filters/effects and print pictures - integrate videos and transition. An optional “Rotate around point” mode is available by using the Ctrl key on Windows and Linux and the Command key (⌘) on Mac OS X, when clicking on the map canvas. In this mode, instead of rotating around the center of the image, the raster will be rotated around the clicked point.

I lost my display a couple of times as well since Tiger due to out-of-scan problems. The solution is easy: In the /Users/<Username>/Library/Preferences/ByHost-directory of the user who changed the resolution you should delete the file that starts with com.apple.windowserver.plist (behind that is some code to identify your computer, in case you have a network home directory.
You could delete this file from from single-user mode, an admin-account, from OS9, whatever you feel comfortable with.
And in my case: I have an LCD (Eizo L557) and merely clicking on the selected resolution (1280x1024) makes the scan frequency go crazy, without a warning dialogue. Even though it is connected through DVI. Very strange, but I think it is just a 10.4.0-thing, will be fixed soon.

Facebook jackpot party. You may also be able to bypass the scan rate problem, and delete the windowserver.plist file, by starting up the Mac in Safe Boot mode (hold down the Shift key at startup).

I believe this is for Macs that have ATI graphics cards. My PowerMac G5 has one of the nVidia cards, and does not have this option in the Display preference panel. Neither does my 12' PowerBook..

sounds to me like laying the groundwork for a tablet mac.. anyone care to speculate?

I'd love it if they released a tablet, but a more present day function is for those rotating LCD monitors like Dell has, 2005fpw. I have one but I can't get this rotation trick to work on my 12' pb. It is a handy feature though, since documents are usually laid out vertically and a vertical screen would let you see more of the document at once. I did see something mentioned that said sub-pixel rendering relied on horizontal displays though, so the color accuracy and even readability goes down when it's rotated.

I believe this will only work if the display has 'Geometry controls'. My Alu 23' does not have these controls. :( I tried in vain to get the drop down menu and ended up typing 'Rotate' in the System Pref Spotlight search box and then selecting 'Screen Image' that dropped down and appeared. Doing this I observed another drop down pane/sheet that indicated
The Geometry tab of Displays preferences is hidden because this display does not have geometry controls.

Hmmm - reading some of the other replies makes me add - I have 2x 2.5GHz PM G5 with the nVidia 6800 Ultra.

Try holding OPTION+COMMAND when clicking in the Displays icon in the System Preferences. ;)
This seems to work with iBooks and PowerBooks.
CAUTION: Try it at your own risk. As it's not shown by default, there may be a good reason for this.

Does not work for me, I have a 17 inch powerbook of the first generation. But I did notice this, if one holds shift-option while clicking on monitor, you get the slow motion version of the transition between all preference pane and the monitor preference.

Works fine for me on my 17' 1.33 PowerBook with the Radeon 9600. Make sure you quit system preferences first before holding option-command. If you get the wrong keys you have to quit the preferences and try again.

Well.. I changed it and took by accident 180deg. After changing, the option was gone, so I was in a little trouble suddenly :) But quitting system prefs and alt-click brought the rotate back and I changed it to normal. I'll try 90deg in a moment. Right now, the anti-aliasing is rather screwed up..

Guys, there is no alt on the mac. There is the Command (or Apple) key, the option key, and the control key.
In this case the poster means option. To get the rotate menu, do the following:
Close System Prefs.
Open System Prefs.
Hold down the option key while selecting Displays
On my Original Titanium G4 Powerbook the rotate menu shows up automatically for the cinema display, but not for the internal monitor. Doing the option trick brings it up for both. Rotating the display on the powerbook is no problem. To rotate it back to normal, just follow the steps above again.

That's funny. My option key clearly also says 'alt'.

FYI, alt is used on a lot of non-US Apple keyboards in place of opt.

Worked for me! Now I can have my MacBook Pro on it's side and use it as a text reader while using an external display as the main display.
15' MacBook Pro (2009) OS X 10.6.4

Oh, I should add I have to have a second monitor hooked up for this to work. If it's just the MacBook by itself it doesn't work.

well i have last 15' powerbook with.. i don't really know.. yeps ATI Mobility Radeon 9700, and i see that option to rotate in displays, but only on external one and i haven't tried it with vga but only DVI. so i do hope we talk about the same thing when some of you guys complain. although this may prepare a path for a tablet mac, still we are mostly going to operate our powerbook sin landscape mode, huh? (although the possibility of reading in bed could be cool, i would still have to remove a few menu icons to make space for anything else than file and edit..)

If you want to read in bed, Preview allows rotating of PDFs. This is very effective and I've used it extensively to read books and manuals in a landscape format.

Apple decided to hide rorate option on some models despite they have capabilities to rotate it. The way to unleash rotating (provided hardware supports the trick) is:
1. Run System Preferences (the point is, it must be just-run, so quit it and reopen if you have it already opened)
2. Alt-click at Displays
3. Select your rotatation :)
If you want to revert to previous rotation, or to standard - close System Preferences and go to #1

Hrm.. not sure what is wrong.. I do have the 10.4.1 update, but this trick, holding down alt/opt when clicking displays (yes, being the first thing i do after opening system preferences from the lil apple drop down menu)
Ive got one of the newer 1.5GHz 12' powerbooks. Id really like to figure out how to flip the display with an apple script, so that i can use the sudden motion sensor to flip the display automagically if i tilt it sideways to read it like a book. I think you can see where this is going. that mouse button is in the perfect spot for 'flipping pages' in an ebook.
=)

Does anyone know if there is a display that sends a signal to the mac that it has been pivoted, so that the display auto changes.
Is this possible?

Zapping the PRAM should have resolved the out of sync/freq problem.. I'm guessing

Nope. Zapping PRAM has no effect.
The only thing that helps is a safe boot. (Boot and hold down the shift key - just like you used to do in Mac OS 9).

This only works on ATI cards. You might have to hold down option to make the rotate popup appear when clicking on displays.

After 'upgrading' my 14' iBook with SceenSpanningDoctor to enable monitor spanning, the ROTATE menu appeared on my external Xeorx 1280x1024 monitor. Awesome.
The only downside is speed on the external monitor. Any dragging of windows is very choppy; probably because the CPU is swithing the X and Y axises on the fly, affecting performance.

On my G4 iBook I was able to do this by hitting 'option' when launching the pref pane. But after rotating I couldn't accesse the option again - I was stuck with an upside-down display. Finally, i was able to undo the action by restarting the computer and repeating the procedure.
I read about this hint on /. in an article about Apple's new patent for a tablet computer.. although who knows what the patent is *really* for.

On the warning for a scan-out-of-range error:
This popped up at MacFixIt a couple of weeks ago with a forum member.
http://www.macfixitforums.com/php/showflat.php?Cat=&Board=tiger&Number=688727
The solution was simply to safe boot and change the display settings and then immediately reboot.

This is the EXACT same hint (without the in-depth detail) the The Unofficial Apple Weblog (TUAW). Here is the link.

I have my high school textbook on PDF, and I rotate my 15 in PowerBook screen to read it.. Which is very helpful.

Rotation Macros Wow

I have a 9800 Mac Edition retail card in a dual 2.0 G5. This option doesn't come up with any key combination that I can find. I can rotate the monitor with the ATI Displays using Versavision but not with the Displays preferences. Turrets turrets mac os.
Any ideas?
I even went back and reinstalled drivers from the CD that came with card and all updates since. This didn't help. When I updated to Tiger, I didn't install anything other than the ATI Displays program, figuring that surely the drivers came with Tiger.

Now if I could only rotate my trackpad. It took me about 10 minutes just to put the rotation back on my ibook after I tried this. Quite a mental exercise. Now I need to go this try this on my 20' imac and buy that vesa mount that I have been wanting.

Does anyone know if there is there an apple script that will rotate the display for me?

I heard that the Cinema Displays overheat if you rotate them.

Rotations Mac Os Catalina

I know its been a year later, but I would really like to get this to work on a laptop of mine. I remember this feature a long time ago, but looked again today and couldn't get it to come up in the system preferences. Is there a preference file somewhere that I could flip my screen 180 degrees.
As a side note, everybody probably knows that holding shift and clicking minimize will make windows minimize/maximize slowly, and there's lots of tricks with that with dashboard and expose and all that stuff. I found one today that I didn't know about tho while trying to get this to work. You used to have to hold Option and click the Displays preference in system preferences, well while holding the Shift and Option keys, it makes the system preferences load in slow motion.
Anyways, any help on this would be appreciated.

it depends on your hardware. If there's no such a menu in the Display preferences, your hardware can't rotate image.

If you're running 10.6 and you need to pivot your display you can try EasyPivot application, it's available on the Mac App Store. [here]
