Why would one of my MacBook Airs be able to Screen Share from work with the iMac at home while the other MBA not...?

I have 2 13-inch MacBook Airs. Also an iMac.
I could ScreenShare from both laptops at work with the iMac at home.
Suddenly I can only do so from one MBA, which sees the iMac, no problem.
But the other MBA cannot sse it any longer.
The MBAs can see each other.
All running the same OS and Apps.
Only difference is...
All have Multiple Apple IDs. ( 2 )
But one MBA was recently set to use the 2nd Apple ID as the main Apple ID
while the other MBA still uses the 1st, as does the iMac.
What is happening...?

That's the reason.
Unless you're using VNC or Apple Remote Desktop (which I assume you are not) both the MacBook Air and the the iMac need to be using the same iCloud account.
System Preferences>iCloud and make sure Back to My Mac is checked.

Why would my late 2012 MacBook Air suddenly tell me "This movie can be played only on displays that support HDCP (High-bandwidth Digital Content Protection)" every time I try to play a film, or TV file?

8GB late 2012 MacBook Air 512GB SSD with iTunes for Mac 12.1.0.50. Yosomite 10.10.2
This happens on movies and TV titles that have happily run before.

It is everything.
Downloading again doesn't seem to work. I deleted all my films and then just re-downloaded Pixar's 5 minute short film Boundin', but the error message popped up as soon as I pressed play.
The only thing I can think of is that last couple of times I ran Disk Utility a new error appeared that I haven't seen before. I have added a link to a screenshot of the Disk Utility report and it refers to "displaypolicyd should be should be 0, group is 244". It says it has been fixed, but the error still persists each time. This may be a red herring, but I can't help thinking that it is something to do with the problem.

I have a one year old Macbook Air 13. I have a brand new 22" external monitor. When I connect my external monitor it initially provides a nice display - very accurate and no distortions. But, within a few minutes the screen begins a incessant series

I have a one year old Macbook Air 13. I have a brand new 22" external monitor. In turning the Macbook and monitor on, the monitor displays very well, but within a few minutes it begins this incessant blinking (temporary black out of the screen that lasts anywhere from 1-5 seconds). This has been going on for a long time (it also happended with my older monitor which apparantly I threw out when I should have kept it thinking it was the problem). From reading various blogs in the Apple support community, this appears to be a widespread problem, but I don't find a solution, only a lot of speculation. I'm very surprised the Apple folks haven't figured this out. As a new Apple user, heretofor, I have been very impressed with the support and effort to get fixes out to users. This, however, has me frustrated to the point of junking my Mac and going back to a PC. I love the Macbook Air and most of the functionality, but I cannot function without an external monitor. Anybody have any ideas, please help. Frustrated, Jim

Your dsplay is getting extended onto the external monitor. Chcnage the setting to duplicate it or only display on the external monitor and you should be fine,
Let me know if this worked for you.

Would you get a macbook air today?

I heard rumours that there would be new macbook airs on or around March. I am 80% sure about this because intel will release its Ivy core on March which apple planned to use for the new macbook air and pro. I actually planned to get it on Christmas but my dad said that it would be be benificial for me to get the new ones on March because I need a faster processor. I actually have a Compaq presario cq 61 which still works fine. I also heard that there would be 15" inch macbook airs so my questions are:
1. Should I wait for the new ones?
2. Would 15" be better than 13" if there a would be?
3. I am still a middle schooler who just writes essays, makes power point, makes songs and simple videos; so would mba be a good choice for me or would a mbp do a better work for me?
4. Any more recommendations?
I expect a really clear answer please! Thank you!!!

1. Should I wait for the new ones?
If you have a computer that suits your needs in the meantime, sure. But no one knows for sure when the new models will be released except for Apple, and they are very tight lipped on product announcements. Also, technology moves fast, so any newly released mac will soon become "outdated", although it can meet a users needs for many years.
2. Would 15" be better than 13" if there a would be?
IF a model was made with a 15" screen it would depend on what features would be offered on the 15" that might not be offered on the 13" (which again, no one knows so that aspect is worthless to debate at this point). Also, it would depend on what size screen preference you have.
3. I am still a middle schooler who just writes essays, makes power point, makes songs and simple videos; so would mba be a good choice for me or would a mbp do a better work for me?
Based on what you say you intend on using it for, it sounds like a fine choice. Just be advised that you can not upgrade anything on a MacBook Air (certainaly not the ram as it is soldered to the motherboard), but after the warranty expires, you can upgrade the solid state drive (flash memory).

I have macbook air late 2010 model... it works fine otherwise but it has started being overheated in normal situations where normally it used to work fine and draining more battery....... battery time is almost half now.
should i reset SMC... would it help?

I'm doubtful it's a missing driver too, but I feel as though it's driver related. The first time XP was installed, after first boot without installing drivers, it was without sound etc, but fundamentally the system worked. Now after first boot, it's very buggy. Thanks for your suggestion Tonny. I ran the tool but it turns out the HDD is fine. Besides, everything runs fine in safe mode.
Does anyone know if (generally speaking) there is any firmware on the graphics card that would get updated via a Windows update? i.e. is it possible that Windows update downloaded a driver for the graphics card that installed new firmware that wasn't all that compatable with XP?

Why my internal speaker of Macbook Air disappear

Why my internal speaker of Macbook Air disappear ? Now no sound come out and cannot adjust volume button which looks inactive.

did you put your Air to sleep with headphones attached, or closed the monitor with phones attached?
Do not sleep your Air (close the monitor with headphones attached) with headphones attached, this is known to affect some Air under Mavericks.
* this occurrence is being looked into.
Much testing on my own and others as well show that, in some instances, this occurs in Mavericks.
If you choose you may contact Apple for an appt and diagnostics.
However as said, refrain from having phones attached when you close the monitor to prevent this until it is resolved
Test this and re-verify
peace

Why would it be preferable to reinstall OS X rather than restore from time machine backup after Internet recovery?

Hello,
I have not been able to startup my less than one year old MacBook Air (had flashing question mark folder on grey screen and startup manager only appeared once but froze) and so finally managed to do Internet recovery.
Now get 4 options:
Restore from TM backup
Reinstall OS X
Get help online
Disk utility
I'm really new to mac and am wondering why the kind user here who has answered my previous questions has recommended reinstall over restore option? And why not disk utility which says it could repair a disk...although it also says it could erase a disk which sounds pretty scary to me!
Also, am I right in thinking reinstall would be like the reformatting I did on pc, ie will get me back to a 'new' system?
And if I choose this option can I then get the majority of my stuff back from time machine backup on external hd?
Thank you for your help with this.

One week old Macbook Pro 17" fuzzy green screen

I have had my Macbook Pro 17" for one week and enjoying it. When I awakened it from sleep, it had fuzzy green lines throughout the display. After browsing the internet for about an hour the fuzzy green lines disappeared and then reappeared randomly. Any suggestions about why this is happening and how to fix this. Thanks in advance.

Welcome to Apple Discussions!
This sounds like it could be a hardware problem of some sort. Best thing would be to take it to an Apple Store for evaluation. Since it's only a week old, you may be able to get an exchange rather than a repair.
Good luck!

Hey kbert73
I would do a transfer of purchases from the phone and not sync. If you sync then it will want to start over and sync music that is on the MacBook Pro. If you want to transfer the music, check out the article below that will give you multiple options on how to move. I have also provided on how to sync with multiple computers.

I have connected my new Macbook Air to my existing Samsung large external monitor with a VGA adaptor but I can't get the full mac desktop to display. No icons but then websites are coming up. Help!

I have connected my new Macbook Air to my existing Samsung large external monitor with a VGA adaptor but I can't get the full mac desktop to display. No icons but then websites are coming up. Help! Further info: I am a complete newbie to Mac. Had three macs prior to 2000 then four PCs. Just come back and struggling a bit with the unfamiliarity. On my old PC laptop I could simply switch from the laptop screen to the large external monitor (and back) with the F4 function key. While I can get the background image from my MBA to display, that's it. Until I noticed on the far left of the external monitor, the very edge of one of the web pages I was on. So Idragged it over to display in the centre. But that's all that's there. And now I have gone out of those web pages but they are still displaying on the monitor. There is some wierd disconnect. I'm sure it is just a setting thing. Will keep searching for answer but any advice welcome!

Your dsplay is getting extended onto the external monitor. Chcnage the setting to duplicate it or only display on the external monitor and you should be fine,
Let me know if this worked for you.

Early 2009 MacBook Air. On startup no keyboard or mouse me to login. Neither is the USB working so I cannot use an external mouse or keyboard either.

Early 2009 MacBook Air. On startup no keyboard or mouse me to login. Neither is the USB working so I cannot use an external mouse or keyboard either. If I keep restarting the machine suddenly sometime I get mouse and keyboard control and I am able to login and work. After sometime though mouse and keyboard Control is lost again and the machine hangs.
Lately another problem has cropped up. Now the machine starts up and seems to work for longer time but I have no 0 key and USB everything else is fine.
What could be the issue

1. Reset PRAM. http://support.apple.com/kb/PH4405

I have a problem syncing iCal on my Macbook air (10.7.5) and my iPhone 4s (5.1.1) over iCloud. The following server error message comes up "The request (CalDAVAccountRefreshQueueableOperation) for account "iCloud" failed." Been to Apple - no luck. Ideas?

The following server error message comes up "The request (CalDAVAccountRefreshQueueableOperation) for account “iCloud” failed." Been to Apple Store - no luck instore, or with Super genius over the phone when with genius in store, taking data in real time via ethernet!
I had to do a full wipe of my system because of time machine back up issues 2 weeks ago, and the error has only occured at some point since then. I only did a drag and drop of my user account folders/files into an External HDD rather than a copy of my user account (advised by the staff in store at Apple to do this) and when reimported, the Mail folders are all present but each message is in a sub-sub-sub folder that is numerically named. I do not have a mirror image of the hard disk prior to the wipe, only a time machine back up from 2 weeks prior to it being done. I am uncertain if this reinstall has caused the issue.
I am not happy to upgrade the software in my iPhone until I have the calendars working. I have purchased Mountain Lion, but again am concerned about upgrading until the issues are sorted.
I have tried the other solutions on here with no luck. HELP please.
Many Thanks.

Progress Update.
I made a back of what existing phtos and Videos I had on my Iplhone. I used Image capture to do this making an entire back up of photos and videoa that were still intact on the phone.
Image capture is god for this purpose, as it does exactly what you ask it to do without applying any rules or squishing the files back into iphote (which might also be corupted)
Image capture wil do the basic function of retriving the contents of the phone and save them as native files on your hard drive.
Once I did this I erased my iphone, and re intitialised it restoring an older back up from icloud.
As the retore was happneing - I did retreive the missing files that cuased the intial beviour as above, and I could play the videos that were missing in the above scenerio. The wierd ting was however that even though the source files were now back on the device, the thumbnail previews were missing. Where I ahd balck thumb nails for server portions of the resotred content.
I then went to bed as the restore is a long process. When I woke up the library had library had cleaned itself up. Mysteriously the prcess had deleted the files missing the their thumbnails.
This is very perculiar and bad behavior.
I am now repeating the process, and will attempt to download the missing content as it is restored and prior to the phone trying to fix itself.
Here are the lessons learned.
DO NOT rely on Photo Stream to keep back ups and synchornise videos from you IOS device. IT DOES NOT SUPPORT THIS CAPBILITY
DO NOT rely on iCloud Back Up alone - always fd an occassional iTunes back up or more reliably still always take a back up of photos and video files using Image Capture to be doubly sure that you a have backd up any content.
DO THIS NOW - dont wait to loose your phone ofr have your phone repaired by replacement at the apple Store. (I did both :-(

I'm setting up my MacBook Air and it tells me to sign in with my apple ID so that I can set up features like iTunes and iCloud and such but when I try to sign in it says there's a server error. What do I do? Do I try to skip the step? How can I fix this?
