Imac and Macbook pro can no longer see one another

I'm not sure why, but all since I upgraded to Yosemite, I can no longer see my iMac on my Macbook Pro and vice versa. I could always see the computer that I needed to connect to in finder, or I could connect with my iCloud password. As of today, I can no longer access my iMac from my Macbook Pro and that's a problem. If someone could provide directions (dumbed down version) explaining how to connect the computers from scratch, I would greatly appreciate it. I am fine with setting it up again but I can't recall how I did it. Thanks so much. I did upgrade both my iMac and MacBook pro to Yosemite over the weekend.

I have 2 IMacs and MacBook Pro- can not work on FCP simultaneously when my network ports are on (open). How do I go about changing this?

Hi!
I have 2 IMacs and MacBook Pro and can not work simultaneously on FCP on all workstations when the network port is open. Can anyone help me on this?

Did you purchase Final Cut Pro from the Mac app store? Or install it from disk? If from disk, you may have installed it on all machines using the same serial number, and using all of them simultaneously violates the license agreement. If you purchase from the App store the licensing is different and that may not apply.

MacBook Pro can no longer see the hard drive

I've got a MacBook Pro Core 2 Duo, 15-inch.
Okay, so I was chasing the nazis out of North Africa in Call of Duty 2 when the game froze. Command-Option-Escape was unresponsive, so I held down the power button to shut the whole thing down. When I brought it back up, I got the flashing folder icon.
After yelling a few words I shan't repeat here, I booted off the installation DVD, then started up Disk Utility to try to repair the disk. However, Disk Utility only sees the DVD; it doesn't see the hard drive at all. Neither does Startup Disk or System Profiler. (The hard drive would be under the ATA section in System Profiler's menu, right? It only shows the DVD drive.) If I try to go ahead with the OS X installation, at the "Select a Destination" screen, where the list of disks should be is disturbingly blank. So according to every method I've tried so far, it's as if my hard drive has been entirely disconnected.
This was my Christmas present, and I was hoping to get at least two years out of it, not two weeks. Anyone have any idea how to get this beautiful machine back on its feet again? I'm familiar with Unix and not afraid of using the command line, but I'm not sure what to try there.

Okay, second question: How does this forum software work? According to the thread list, someone named MacWizard has replied to this thread, but I can't see it.
MacWizard, if you could email your reply to spearbrave at gmail point c0m so I can read it there, I'd appreciate it.

If you can't get dragging to work, just click on Safari from your Applications folder, and it should appear in the dock. Then you can right-click on the icon and PIN it permanently there.

IMac and Macbook Pro no longer connecting to the Wifi?

Hi there,
I've been in London this weekend, only to return home to find issues connecting to my wifi. Weirdly, it's only the iMac and Macbook Pro having trouble, everything else is connecting fine e.g iPad, Phone, Android Tablet etc.
I'm getting disconnected around every 20 seconds and cannot figure it out! It's so frustrating as I'm wondering if there's been an update released for OS X that it has downloaded recently? Especially seeing that when I run windows from bootcamp on my iMac, it doesn't disconnect. And I also don't believe it's an issue with the hub.
Has anyone got any suggestions? I've tried removing the network and re-adding, help for about an hour but still not much use.
Thanks, Matt

I'm a new potential FCP X user. Can I buy software to load onto my imac and macbook pro or is FCP X only available as a download? I'd like to be able to edit on the road.

Here's a short tutorial video about how to move back and forth between your base computer and the on-the-go machine. Very important info about which things can be copied within Finder and which things MUST be copied from within FCP X. Best wishes.

thank you, I have the adaptors so glad that would work. I just heard adaptors burn out often. So Just thought for my main iMac computer, a plug would be best. I will get one once I move.
Any other suggestions or things I should know about apple products in Ireland. I know there are no Apple stores there.
An adaptor doesn't burn out. It merely serves as a means to connect the power prongs on your device to the power supply.
I believe you are thinking of a transformer, which you do not need. A transformer converts one voltage to another.
You don't need to do that as the power supply of modern electronics can take almost any worldwide voltage.
Look at the label on the device. It should indicate the input power acceptable of 100-240 VAC, 50-60 Hz.
Additionally, I found the adapters cheaper in the UK than I found them in the US. They were available in most supermarket chains. I wasn't in Ireland, so I can't say one way or the other.
If you have something that doesn't have that input power spec, it would require a transformer.
On other items like electric clocks or things with motors, you can connect them up to a transformer and the voltage will be correct, but the frequency may not. For clocks, that will cause them to not keep time well. For motors, they will burn out.

Can some one help me reinstall my MP640 software on my Imac and macbook pro? as the software does not recognise os 10.7.5

My Imac and macbook pro stopped accessing my MP640 via the home wifi set up, so I sent all the canon software to the trash on both computers, thinking I should reinstall the software I got with the printer, but the software does not recognise os 10.7.5. I am using a netgear modem. I also use time machine to back up to time capsule.

My new IMac and Macbook Pro are each loaded with Mountain Lion. Have Office for Mac also
When I try to see my Grandson on webcam out of state the login will not activate. For PC use I needed Java and Active X to let it run. My Java is checked as ready to go but nothing happens. Otherwise these are great computers. Please help me through the process. The Geniuses at my apple store can't understand what to do.

By default, OS X does NOT come with Java installed nowadays. You need to open the Java Preferences app found in Utilities; when you do that the first time, it will inform you of the fact and offer to install the product for you.
Afterwards, due to a major security issue we had back in the first quarter of the year, the plugin is disabled by default. You need to revisit the Preferences and enable manually. It will auto-disable if unused in awhile.
Lastly, you may have to adjust which Java instance is being used, the 32-bit or the 64-bit. Default is 64-bit, but some applets crash & burn or outright refuse to run in such a platform. You can prioritize which version you prefer by dragging on top in the Preferences.

WD My Passport 1TB USB external drive randomly ejects from my iMac and MacBook Pro.
The drive is approximately 4 years old. When the drive is plugged in, I can see the data. It appears to be working properly. The only problem is that everyone of my Apple Machines are ejecting it. Several years ago, this drive connected to Mac machines with no problems. I have tried two separate USB cords. I have updated the firmware. I have tried it on my MacBook, two different Macbook Pro's, and my iMac.
All give the same result of random ejection of the drive and the error message of:
Disk Not Ejected Properly
Eject "1TB Passport HD" before disconnecting or turning......
Searching through the web, it seems this is an common/known problem. Does anyone know the solution?
Thanks,

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

How do I set up LiveRig or TouchOSC with Mainstage 2.2.2? Both apps send signals but none are received by Mainstage and both the ipad 3 (6.1) and macbook pro (10.7.5) see each other via WIFI?

As I said before both app's send signals but none are received by Mainstage and both the ipad 3 (6.1) and macbook pro (10.7.5) see each other via WIFI on the network set up, which I think I did right. I have tried MIDI Disigner and Mainstage shows MIDI activiti, what can I be doing wrong?
Thanx in advance.

I agree anti-relay can be using UBE feature. However, there is serious problem in reject the spam mail. My nms is using UBE feature to stop spam mail. According to the work flow of the UBE, the mail is received by nms completely and UBE is going to invesgate the mail address. Although UBE can stop the spam mail, the spam mail have a trouble in returning the mail to the sender. The reason is the sender address is usually not existed in the world. That will cause a lot of mail waiting in the mail queue.
In my experience, do not use UBE for anti-relay.

IPhoto not working after trying to share iPhoto between iMac and MacBook Pro

I tried to share my photos on both my iMac and MacBook pro. It deleted all my photos in my MacBook and now it won't let me even open iPhoto in my iMac and gives me the following message "You have made changes to your photo library using a newer version of iPhoto. Please quit and use the latest version of iPhoto."
How do I rectify this? Purchase iPhoto from the App store?

What version of iPhoto do you have on each system?
It sound like you propbably have a newer version of iPhoto on the MBP - and thay you opened the iMac iPhoto library using the newer iPhoto - if you did you were warned that doing this would convert the library and that the older version of iPhoto could no longer open the library - the error message you list says that this is what you did
If you did the only options are to restore your iMac backup from before you converted the library, upgrade iPhoto on the iMac the same version you have on your MBP purchasing from the App store or use iPhoto Library Manager - http://www.fatcatsoftware.com/iplm/ - to downgrade your library
