I have an 2009 27inch imac and a 2012 macbook pro

Hi... I have an 2009's 27inch imac and a 2012 macbook pro. Can I use the imac as an external monitor? If so, what is the cable to connect both?
Tnks in advance!

Welcome to Apple Support Communities
Late 2009 and Mid 2010 27-inch iMacs can be used as external displays for other Macs. See > http://support.apple.com/kb/PH11302
Your iMac has got Mini DisplayPort, so you can use it as an external display for your Thunderbolt Mac. You only have to get a Mini DisplayPort cable to connect both Macs, and press Command and F2 keys on the iMac to enable Target Display mode.

I have Thunderbird installed on my IMac and on my MacBook Pro, The MacBook Pro Thunderbird is already set up. How can I copy Thunderbird settings to the IMac?

I have installed Thunderbird on my IMac and on my MacBook Pro. I have already completely set up Thunderbird on my MacBook Pro. How can I transfer all of my settings, bookmarks, etc., from my MacBook Pro to my IMac? Also, can I automatically keep both copies of Thunderbird synched so that changes on one computer are recognized on another computer.

Create a new profile and copy the old one over it.

Hi, I have backed up 2 IMACs and one Mac Book Pro but for some reason, the 3rd IMAC come up with this problem: The backup disk image “/Volumes/Data/Anthony’s iMac.sparsebundle” could not be accessed (error -1). Why? The computer system is up to date and I have had no issue with the other computers, just this one.
Many thanks

Can I have my I tunes library on my iMac and my new MacBook Pro

I have just purchased a new MacBook pro retina display however my iTunes library is on my desktop IMac. Is its possible for me to see the same library on the 2 devices and if so how can I do this?
Thanks

Hi,
That is correct.
You can download your music on to your MacBook but if hard drive space is an issue, you may wish to consider iTunes Match. http://support.apple.com/kb/ht4914.
You set up match on your main computer and once this has been done you can sign into iTunes and match on your MacBook. You will be able to stream music anywhere you have a wifi connection.

I took my iMac to be fixed and when I got it back, mail was not set, so I called Apple and they helped me set up mail. Now the new mail goes to trash and there is no number by the 'inbox' to tell me how many new messages I have. I cannot save a draft to 'drafts.' There is a large number by 'trash' (I think all mail went to trash - including drafts). When I send myself an emai, it goes to trash also. This is on both my iMac (the one taken in) and my MacBook Pro (same emails) which was not taken in.
I went to 'rules' but have no idea what to do there. There are no rules in the rule box. When I click 'add rule' it puts 'rule 1' in the rule box, but since that was not there when I took it in, I delete it to have an empty rule box.
Can someone pleasehelp me. I am completely stupid with all this. Do not under stand what is suppose to be set up in 'rules.'
Thank you so much,

Now new mail is coming to both computer's inboxes but there is no number on the stamp icon on dock to show number of emails on the iMac. Nor is there a number by either email address under MAILBOXES/inbox (sidebar) on the iMac. This number is showing on MacBook Pro.
I also can save drafts now on both computers.
Seems the Pro is fixed and the iMac is only missing the numbers on dock icon and by addresses in inbox.
Now that the problem is less, I feel i am wasting your time but will continue so maybe I can get those numbers back.
Two emails > AT&T email and gmail.
Apple's Mail program for email - yes, and gmail.
IMAP for both accounts.
Did not change mail configuration on MacBook.
The iMac and MacBook Pro have the same mail configuration except in Accounts/mailbox behaviours/store draft messages on the server was not marked on MacBook > it is now.
'Store junk messages on the server' was marked on one computer for gmail, but is unmarked on both now.
On the iMac, Accounts/Accounts info/Outgoing mail for gmail is smtpgmail.
On the MacBook Pro for gmail it is smpt.gmail.com (plus) my email address.
Rules/Add rule window, on the MacBook third line is 'Any Recipient', on the iMac third line is 'From."
The last box on that line has my email address on the MacBook.
The last box on that line has the last address I sent an emil to (last night), on the iMac.
On the last line on iMac, no box was selicted for 'to mailbox' > I choose 'inbox' because it is on the MacBook Pro.
Now I have a Rule #1 and am not sure I should have because there was no rules marked when I took the computer in.
Thank you. I relized I had done the labeling wrong when so much of my question appeared twice and no one else's did. I know how to do it now.
Thank you so much,

1 x iMac and 1 x Macbook Pro with iPhoto 11 on each and an external network hard drive

Sorry in advance if this has been asked already - I scrolled down to see but could'nt find it......
Anyways, here is my situation: I have approx 7 yrs worth of digital photos stored on my external network hard drive. I've recently turfed my Dell and replaced it with an iMac as my family's main computer. Now I have 2 Apple computers at home - the iMac and a Macbook Pro that I am its only user. Both have iPhoto 11. I've been playing around with the pgm and have been importing photos from my external network hard drive (not many but enough to get the idea of iPhoto) on both computers only to realize that the work I do on one is not reflected when I go on the other. After reading some of the comments in this forum, I now realize that a copy of the pics go right on the computer's hard drive.
Is it possible to just edit, etc the pics on my external network hard drive and replace the old pic with the edited one?
Also, is it possible, for the work I do on pics on one mac to appear in the other's iphoto library? Meaning, when I do "events" and "faces" on one mac, is it possible to see that work on the other?
If not, then at this rate, I will have 3 copies of the same photo - one on the external network hard drive, one on the iMac, and one on the Macbook pro!!! I've read some stuff ref iCloud and it sounds like this could be a possible solution but am not sure.
Any help would be greatly appreciated!!
Thx,
Craig

Sort of?
Is it possible to just edit, etc the pics on my external network hard drive and replace the old pic with the edited one?
That's a straight no. iPhoto is a Digital Asset Manager and as such always preserves the original file. Basically, to iPhoto, your original file is the "digital negative" and it protects that the same way a film shooter will protect his negative. So it will never edit or replace an original file.
Also, is it possible, for the work I do on pics on one mac to appear in the other's iphoto library? Meaning, when I do "events" and "faces" on one mac, is it possible to see that work on the other?
There are a couple of ways to make this happen.
A: If you only edit nd manipulate on one machine, then simply back up the library to the other machine. Net result: The same editions of the same photos on both machines.
B: Create one Library and share it across both machines - best way to do this is to put it on an external hard drive and then plug that into whatever machine needs the library at whatever time.
But... This can't be your "network hard drive". The disk needs to be formatted Mac OS Extended (Journaled)
I suspect that iCloud will make all of this moot, but until we see it in action we won't know for sure.

I installed my new iMac with my Macbook Pro 2008 backup and created a network with the iMac and now the Macbook Pro cannot get internet.

I installed my new iMac with my Macbook Pro 2008 back up. I created a iMac network with Airport extreme, but now my Macbook Pro cannot get internet. any ideas on why or what to do about it.

Hello 1BillyMac,
It seems you have a network conflict that isn't allowing your MacBook Pro to connect to the internet. This may be caused by both computers sharing identical network settings. You may want to consider creating a new network location on your MacBook Pro to assign new network settings. The following article will instruct you on how to do that:
OS X Yosemite: Add a network location
A network location is a group of network settings
A network location is a group of network settings for your various network services (Ethernet or Wi-Fi for example).
If you often change network settings, you may find switching between locations quicker and easier than repeatedly modifying individual groups of settings.
For example, you might want to make a location for “home,” where you connect to the Internet with a telephone modem, and a location for “office,” where you connect to your company network and the Internet using Ethernet or AirPort.
Choose Apple menu > System Preferences, then click Network.
Click the Location pop-up menu, choose Edit Locations, then click Add .
Enter a name for the location, then click Done.
Enter settings for each network connection service you want to use in that location.
After you create your locations, you can switch all of your network settings by clicking the Location pop-up menu and choosing a different location.
Thank you for contributing to Apple Support Communities.

Drobo Pro, iSCSI and the 2011 Macbook Pros

I ran into awful connection issues using iSCSI and a Drobo Pro with my brand new Macbook Pro. Nothing turned up on google, so I thought I'd get the ball rolling:
Drobo Pro was "disconnecting" from my brand new Macbook Pro while doing simple Log&Transfer work in Final Cut Pro. This is a process that I've done countless times on my C2D iMac and Core Duo Macbook Pro. While connected via iSCSI, L&T would completely freeze after a few seconds of working. In turn, finder would freeze and no data from my Drobo Pro would be accessible until I did a hard reboot on the computer. All of this happened regardless of the state of the AirPort, network settings, Font Book settings or PRAM zappage. It felt exactly like a full-on disconnection, but without any acknowledgement from OSX about the disconnect.
The fact that my Drobo works perfectly with the other two Macs convinced me that it was a hardware issue on the MBP. According to Apple, there was no difference with the Ethernet architecture between this MBP and any other Mac, and according to Drobo, there was no reason that the iSCSI initiator would do anything differently. As it turns out, there is something about the new Macbook Pros that everybody overlooked:
By default, the 2011 Macbook Pros boot into 64 bit mode. My iMac doesn't. My CD MBP doesn't. This is the key to the issue.
After reading up on problems with 64 bit OSX and Drobo Dashboard's iSCSI on the Drobospace forums, my issues turned out to be very similar to everybody else's: Drobo's speed into my mac was at 1MB/s or less. It wasn't a total disconnection, but a drought of data.
Has anybody else run into this issue with iSCSI and the new Macbook Pros? Hopefully as it comes up more often, more people can bump into this post and save themselves a few hours of troubleshooting.

I may not be of any help, but yes, I have issues too.
We had a DroboPro connected to our Mac Mini Server (late 2009) and shared to our network with plenty of speed. We just upgraded to a MacPro 2x2.4GHz Xeon (mid 2010) and now my DroboPro gets around 1MB/s when connected via iSCSI.
I've tried as many connection configurations as I can think of, and I can't get it. Actually, I did have it working well briefly last night, but then I lost it again, and I'm not sure why. It could have been because I installed some other software, but I'm not sure.
Could it be that I still have Drobo Dashboard (and therefore the iSCSI initiator extension) installed on other computers in my network? But I can't even get it to work when all the other computers are off.
Frustrating.

I have a mid-2010 iMac and just purchased a 2TB TC, can't join existing wireless network with AC standard so attached to iMac via ethernet with TC wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. working fine with TM

I have a mid-2010 iMac and just purchased a 2TB TC, I just found out that it can't join existing wireless network with new AC standard so attached to iMac via ethernet with TC's wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. It is working fine with TM. My cheeper seagate drives etc kept crashing, so i didnt trust cheeper back up options anymore. Connected those drives to TM via firewire and could see the drives and access them.
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc. I connect to the internet via airport only and it is pretty fast. Getting over 50mbs downloads and over 30mbs uploads. Plus everything in my home it connected to my fios router, airport express for music streaming, two apple tvs, vuezone camer system. I really didn't want to monkey around too much with my system. But are there other options to connect the new TC. Can't find info anywhere for this and called apple who gave me the info above. after hanging up, i see that i cant access my TC and I am wondering if i would have to reset it to turn wifi on again to make changes to the drive, turn off blinking light or repair it in disk utility if it should become corrupted.
For other with similar issues i did solve some other problems: when i connected it to my ethernet port on my iMac wifi stopped working. Found that I had to turn off the ethernet in the system>network screen, but then TM didn't see the TC so i restarted after changes and then it saw it.
Now a rant. I can't believe in this wireless age that Apple would make a product that cant join a wireless net work. The apple rep said i could return it and look for the previous TC that would join an existing wireless network. Are we going backwards?
Thanks!

Ok... it is getting a bit clearer but there are still some questions.
I connect to the internet via airport only and it is pretty fast.
I was assuming airport in this statement in your first post meant the TC or the Express.. but I now realise we are still in the mass confusion stage where apple calls everything wireless an airport. So what you mean is the airport internal card of the computer??
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc.
I think this is mistaken.
Putting the TC in bridge mode plugged into your FIOS will not slow the network.. nor will it cause mail or port issues.. in bridge the TC is just a fancy WAP and switch plus the network hard drive.
If the computer is close it will be faster than the FIOS.
You can run both wireless networks with different names.. so it is clear which is which. But you can also setup roaming so the computers themselves pick which is the best wireless.
I tried extending the wireless net work and tried joining wireless network, but the TC kept crashing and I had to keep resetting the TC. the Apple support person said these, extend wireless network and joint wireless network, are no longer a connection option with the new TC because of the new AC protocol.
Thanks again!
You cannot extend to a non-apple wireless router.
You cannot use join a wireless network because when you do the ethernet ports will be cut off.
But that has not changed.. I don't think Apple support is correct.. there has been no change with the AC model.. it is simply a fact that apple routers do not work in join wireless mode other than as a dumb client. The same applies to AC as to the earlier version.. but I have asked another person to check this.
Join in the express is the only apple router that still allows an ethernet connection.
For now you best use of the TC is bridged to the FIOS. Wireless you can sort out between several options.

I have a music library on an iMac and I got a new iPhone and a new MacBook Pro and I want some of the songs from the iMac library to be on my phone and my MacBook Pro and I have a new Apple ID on my phone and my Mac book pro

I have a music library on an iMac and I got a new iPhone and a new MacBook Pro and I want some of the songs from the iMac library to be on my phone and my MacBook Pro and I have a new Apple ID on my phone and my Mac book pro, is this possible if so how do I do it?

Providing specifics on all the ways to do this will take more time than I am willing to spend here these days. You can do some of this with Home Sharing. You can transfer the entire library from one computer to another, If you do that you can delete what you don't want from the transferred library.
Quick answer if you use iTunes' default preferences settings: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Open iTunes and immediately hold down the option (alt) key (shift on Windows) so you get a prompt to select a library, then guide it to the 'iTunes Library.itl' file in the moved iTunes folder. If you put the copied iTunes folder in the default location of Macintosh HD > Users > *User Name* > Music then you don't even need to start with the option key held down, iTunes will automatically look for it there. (Make sure there isn't anything already in the iTunes folder there that you want to keep since you will be replacing it with the one you are moving.)
You do not want to use a new AppleID. Change the AppleID on the new phone to the old ID. Purchases made with one AppleID cannot be transferred to a different one and it will be a royal pain to manage two Apple IDs.
Change iTunes Store account on an iOS device - Log out of your current account with Settings.app > Store (Settings > iTunes & App Stores on iOS 6) > tap on your AppleID. Log in with a different account. Note, turning on automatic downloads or re-download past purchases may tie the device to that account for 90 days - http://support.apple.com/kb/HT4627 https://discussions.apple.com/message/18484935 - "In order to change your Apple ID or password for your iCloud account on your iOS device, you need to delete the account from your iOS device first, then add it back using your updated details. (Settings > iCloud, scroll down and hit "Delete Account") When you delete your account, all the data that is synced with iCloud will also be deleted from the device (but not from iCloud), but will be synced back to your device when you login again."

Hi Fid
Your mac is fine but you need OS X 10.8 Mountain Lion or newer and your profile says you have OS X 10.7.5 Lion. You need to get ML as a purchase from the app store as mirror is a new feature with that OS.
The alternative is a third party app called airparrot.
