Since upgrading to mountain lion on my macbook pro, i cannot email photos from iphoto.
i can select the picture but when sending it, an error symbol appears.
Any ideas ?

This doesn't work for me at all. I tried entering exactly the same information that I used to set up my regular email account and I'm still getting an error message. I even tried switching to using my gmail account and neither one worked. Then it got hung up and had to repair my database! I have a lot of photos on my Mac (thank goodness they're backed up) and I was really sweating it for a moment.
Apple is so easy until it's not. I find this to be really aggrevating and I'm irritated that it hasn't been fixed. In fact I did an online search and someone described this same problem in detail and it was exactly what was happening to me. Same error messages.
I'm frustrated that Apple keeps updating it's operating system and then we go through these glitches.
And while I'm at it, I have never had such a frustrating time using my login information as I have to get into this forum! Why do they make it so difficult? There's just something about the way it's worded that get's me messed up every time. Meanwhile, at least get iPhoto fixed!

Just installed Mountain Lion, and my Mac won't boot correctly. What should I do?

So I stupidly decided to "upgrade" to Mountain Lion this evening. I downloaded ML, installed it, and now whenever I try to boot my Mac I can't get anywhere. The apple logo comes up and the spinning wheel below it starts up, but then it stops and restarts itself over and over again. I can boot in Safe Mode and I have verified the disk and the permissions (there were no issues.) Any suggestions on how to get it to boot normally? If it helps, I have a 2011 Macbook with 8GBs of RAM. I did have Snow Leopard before I tried upgrading to Mountain Lion.
Also, on a side note, I have my original install DVDs that came with my Macbook... if nothing else works, can I use these to revert back to Snow Leopard? I don't care if I have to clear my entire computer, I have everything I need backed up (and not through Time Machine. I just have the files I want.)

Have you checked that all your apps are compatible with Mountain Lion? Check that the apps are supported > http://www.roaringapps.com If you have apps that aren't supported, start in safe mode and uninstall them. Then, restart and see if Mountain Lion starts properly.
Another thing you can do is to reinstall OS X again. To do it, hold Command and R keys while your computer is starting and reinstall OS X.

Of course. You have to erase the hard drive and install Snow Leopard on your hard disk, but first try to solve the problem with Mountain Lion

Right after upgrading to Mountain Lion on my MacBook Pro, some websites on Firefox won't load videos and some look like html (or something like that).

I've used Firefox for a while on my MacBook Pro (about 1.5 years old) and it's worked great. Should be fully updated too. Immediately after I upgraded my OS to Mountain Lion, some websites wouldn't load correctly (looked like html or something). Also some websites like YouTube show video fine, but then at least one other website doesn't show the video window at all, much less play it. Safari doesn't have that problem. Any ideas?

Did you try turning off power nap?

After ransomeware on my macbook pro it is really slow, is there anything i can do to improve this?

After getting ransomware on my macbook pro it is really slow, what can i do to improve this? I cleared it from the screen by restarting and holding shift

If you held down the shift key at startup then you are now booted into Safe Boot Mode which is always slower than the regular boot.
Restart the system without holding down the shift key.
What do you mean by Ransom Ware? did you get a POPup claiming to be from the FBI?

Please google search for "Mountain Lion disk crash" before upgrading you mac pro. You might need to replace you Mac hard drive after the upgrade.So many people had the same problems including me.
Be aware of the Mountain Lion upgrade problem.

Selling macbook Pro 2011. It came with Lion, I upgraded to mountain Lion and Mavericks. Can license be transfer to new owner? how?

Good question now that Mavericks is free to all.
It used to be - and is probably still the case - that to comply with the license you should erase and re-install the OS that came pre-installed on the Mac when new. If there were restore disks they needed to be passed on with the Mac.
I'm happy to be corrected on this by someone who's more au fait with the legalese, but an upgraded OS is tied to an AppleID whereas the original OS is tied to the computer, not an AppleID.
My guess is, that if you launched the Recovery HD, erased the drive using Disk Utility and re-installed the OS, Lion would be installed.
Be interesting to see what others say.

I have an Epson scanner that is apparently no longer supported because it is a PowerPC app. It's a very good scanner that worked fine until I upgraded to OS Mountain Lion on my MacBook Pro. Any suggestions on how I can continue to use it?

Just upgraded to mountain lion and my HP Laserjet p1102W won't connect

Just upgraded to mountain lion and my HP Laserjet p1102W to print (worked fine via USB with Snow Leopard; I never had set it up wirelessly, though had wanted to do so.) HP site said if printer worked with Snow Leopard nothing would need to be done; update of drivers would be automatic within Mountain Lion upgrade. No such luck. My Macbook Pro and HP Printer are not talking to each other. HELP, please!
I have a Macbook pro.
When I tried to print, I was told to get new drivers from HP. HP site says what I wrote above, that I need do nothing if printer worked with Snow Leapord. Also read that a new HP Laserjet would need to be connected only via Airprint. So, I have deleted the printer from the print queue, thinking that might help, but I can't find how to install it via Airprint?? After deleting the printer and having no luck with connecting wirelessly, I tried plugging in USB from printer to MacBook pro, too, thinking maybe that would help, but there is no recognition at all.
What am I missing???
Thanks!

Airprint is for IOS devices and thus has no relevance to this issue.
Connect the printer to your Wireless Network and use Bonjour to detect nd connect it.
That's wrong. AirPrint is not just for iOS devices. Since HP doesn't provide drivers for this printer, they say to use AirPrint:

I upgraded to mountain lion and now iMovie dose not see my Canon XHA1 . Can anyone help?

I upgraded from the app store. It is actually quite awhile ago so I do not remember how. I think I used a thumbdrive to create some type of file. No I do not have any backups. My iLife CD is nowhere to be found because this is a very old macbook pro that I've had for a couple years.
Thanks for taking the time to help

I would like to leave my iMac on Snow Leapord to use Power PC software, and run Mountain Lion on my Macbook pro. I am getting an iPhone 5. Is there a way to use mail on all of them?

I would like to leave my iMac on Snow Leapord to use Power PC software, and run Mountain Lion on my Macbook pro. I am getting an iPhone 5. Is there a way to use mail on all of them with the same accounts?

Any IMAP e-mail account can be accessed from all devices just fine. You don't need to upgrade from Snow Leopard to be able to access an IMAP e-mail account. However, Snow Leopard won't have built-in support for iCloud. As mende1 points out, you can still read your iCloud e-mail from Snow Leopard, but you have to set it up manually. You won't be able to do things like sync your iCloud calendar or addresses with iCal or Address Book on the iMac, though.

I upgraded to Mountain Lion and now I can't use any of my software!

What a disaster and huge mistake. Upgraded to Mountain Lion and now I can't run Autocad 2012 for Mac, any of my Adobe Creative suites software such as Photoshop, Illustrator.. and now I can't even do upgrades because Mountain Lion doesn't allow me to launch DMGs. I've lost thousands of $'s in software, not to mention time, but most importantly now I can't even work! I just tried to revert back to Snow Leopard by intalling it back in my hard drive and it won't let me. I never used Time Machine. Is there any way on earth I can revert back to my old operating software??? Please help. And if you haven't upgraded yet and are thinking about it. BEWARE - and don't do it. I've been reading that Mountain Lion isn't working with Microsoft applications either. Omy...I haven't even checked that.
and of course no one at Apple support can or will help me

It's not my Microsoft that I use much or am worried about. I can't run AutoCAD. and I can't update AutoCAD either. When I try to mount an update just to get it working, it says it can't run the DMG file. Apparantly this new platform doesn't use Rosetta - which is needed to run any of these updates or downloads. ***? and then When I try to open CS4 appliations - Adobe Photoshop, Illustrator, or InDesign - I get the message "Licensing for this product has stopped working - Error 150:30 - ***?
So basically I can't use ANY of the programs I ran before. And yes I have googled desperately all day. Adobe has some suggestions - like deleting a Flex files - which I did...Defragmenting - which I did. And most importantly provides am Adobe Licensing Repair tool to fix - which I can't open because Mountain Lion won't mount the DMG in order to run it! It's a complete disaster and I don't have the money or time to purchase and or reinstall everything. I am just screwed.
No you are not, calm down, cbs20 already gave you the answer on opening dmg files, updates are available for most of your programs and I assume you have licenses for the Adobe products. AutoCad you'll have to wait for.
And please .... Start Backing Things Up, you could lose it all without one, work included.
