Can't access my gmail after installing mountain lion

Hi everyone,
I installed mountain lion tonight and my hotmail and gmail accounts stopped working? My iCloud account is fine as you would expect but and my connection is fine! When I try to access hotmail or gmail it says there is a problem with the network? Any ideas?

Hey guys I've found the solution for this problem!!! You will can continue using the wifi conection! My Mountain Lion language is portuguese so i will translate how i think it is in english... go to sys preferences, click on network, than select wifi and click on advanced button, select the hardware tab, on set check it as manual, and then check MTU mode as personilized. It will show a number (problaby 1500) set it as 1400 or lower and click on ok! After that, everything will work again! I hope that helped you all! Thanks.

Can't open mission control after installing mountain lion

Mountain Lion is working smoothly for me except that I can't open mission control. I became aware of this because the "hot corners", which I use frequently stopped working for me. Maybe there's a preference file somewhere I can trash? I can't seem to find anything in the library.

I'm having the same issue. Not only the hot corners not work for mission contral, but neither do the keyboard shortcuts. A restart fixes the problem for me, until my iMac (2011) goes to sleep and is woken up again. After that, the mission contral functionality no longer works, and neither does the "show desktop" hot corner functionality.

After installing Mountain Lion two drives on my network cannot be accessed. I am using Parallels to utilize QuickBooks ERP. The programs and data are on the drives that I can no longer access. Suggestions?

After installing Mountain Lion on my Mac Book Pro, I can no longer access two shared drives. Diagostics cannot solve the problem. I am using Parallels to run Qucikbooks ERP on these shared drives. How do I get my Mac to see these drives and access them?

Don't know what to tell you, but I also have an AEBS-Gen5 with a MBP Retina and Mac Mini using WiFi. Both are running Mountain Lion and I don't have any WiFi connection issues. Two iPhones in the household use WiFi with no issues along with a printer and 2 Windows 7 laptops.
First thing I would try is to shutdown all computers connected to the AEBS. Then power off the AEBS and finally the cable/DSL modem. Then reverse the order and power on the cable modem, wait for all the lights to be solid, power on the AEBS, wait for the light to show solid green; then power up a computer that uses WiFi.
If the above doesn't work, you might try repairing permissions via Disk Utility. If that doesn't help maybe a PRAM reset would work.

Numbers does not open with the main user after installing mountain lion. It works flawlessly when I use the second account on my mac. What got corrupted in the admin-account, something in the user-library? How can I fix it? I´m kinda desperate...

Looking forward to hearing from somebody with a littlemore expertise than me, Chris

you can remove preferences files by navigating to the Preferences folder for your user as follows:
0) Quit ALL iWork apps (Keynote, Pages and Numbers)
1) from the Finder select the menu item "Go > Go To Folder…". This will bring up a dialog:
2) enter the path "~/Library/Preferences" (no double quotes)
3) find the files:
com.apple.iWork.Keynote.plist
com.apple.iWork.Numbers.plist
com.apple.iWork.Pages.plist
and move these to the trash. I would NOT empty until later.
4) restart Numbers

After installing Mountain Lion on my 17" MBP G-RAID mini connected via Tempo SATA Edge ExpressCard34 is no longer recognized. I restored icon and access by removing 34 card and substituting FW800 for eSATA. Any fix for the higher speed connection? TIA

Looks like the Silicon Image drivers were moved to the incompatible software folder during install/upgrade.
Downloaded latest drivers, errored out of install claiming that the drivers were from an unknown author!!!
Emailed their tech support this evening describing problem.

After installing Mountain Lion, why is there Yahoo access for one user but not another?--both are administrators.

After installing Mountain Lion, why is there Yahoo access for one user but not another?--both are administrators.

We've had several instances where we have had to run chkdsk on arrays with over 1m files. Average completion time is approximately 72 hours. The maximum downtime window they have available is the 64 hour weekend window. File sizes and number of files were
much smaller then than they are now.
The idea, in theory, was to use VHDs to compartmentalize the data into smaller volumes which could be more easily managed. It would also improve performance when transferring these compartments of data as they would use sequential read/write rather than
fragmented/random. This idea was never fleshed out in entirety, they don't split data up into little containers, but simply into big ones per project. Hence the 11m files in one container that I am currently trying to diagnose.
Some other important facts: The VHD in question is mounted in B:/project/ as this server also allows remote workers to log in, but they are restricted to see only data in E:. Disks A-D are hidden via group policy.
Update: icacls is failing on a large number of files within this dataset. I counted the path characters to ensure it wasn't the 255 character limit I was encountering and verified that the paths being blocked are only about 150 characters long. Once it finishes,
I'll have to try taking ownership and then re-running it. At this point I still have no idea how long to expect. I'm running out of time as the environment will be in use again at 9AM tomorrow morning.

MacBook Air late 2010 very hot after installing Mountain Lion? Can i back to Lion?

My MacBook Air, late 2010, is very hot and the vans are going too speedy after installing Mountain Lion. Can I deinstalling Mountain Lion and returno to Lion? What are the steps for this deinstallation? Thank you.

Technically, there is a way, but it is definitely not something I would recommend, as downgrading isn't usually supported/encouraged.
I found a website that has instructions but it clearly states it's not for the inexpert, so proceed at your own risk. Also, I don't think you can download Lion from the AppStore anymore?

Can No Longer Get Camera Photos After Installing Mountain Lion

After installing Mountain Lion, I am no longer am able to see pictures from my digital camera thru the USB port. This camera has worked for years with my iMac, but not anymore. Anybody else having this issue after installing the newest system?
Dick

Paul_31:
I have not tried to import the photos directly into iPhoto. However, I did remove the SD card from the camera and plug it into a USB card reader, and my iMac would NOT read the photos that way either. I took the camera and plugged it into my Win. 7 laptop and the pictures showed up nicely, so I know the camera and the card are Ok. My iMac has been working strangely since I installed Mountain Lion. I'm getting lockups using iMovie too.

Can't activate FaceTime after installing Mountain Lion

After installing Mountain Lion, I opened Facetime and attempted to activate it using my Apple ID, this was what I got:
"The server encountered an error processing registration. Please try again later."
I created a new Apple ID and tried again; same thing. I contacted Apple Support for help. After hours of instructions, reboots of my MacBook, reinstalling Mountain Lion, and a lot of patience later., the outcome was the same. It just couldn't be activated.
Today, I tried to activate Game Center, know what? Similar problem. This was the error message I've got:
"The requested operation couldn't be completed due to an error communicating with the server."
Any idea?

Does anyone have an email client that is working with Mountain Lion? I'm giving up on Mail after installing Mountain Lion

Hi
I give up. I just cannot see my exchange inbox in Mail after installing Mountain Lion. My mail is not being deleted. Its still in my inbox I just can't see it. I've tried everything suggested on the forums and nothing is working for me.
My productivity has completely stalled and I really need to move to an email client that is going to work seamlessly with Mountain Lion.
Any recommendations?

I have the same problem. Upgraded to ML, and my Mac Mail suddenly can't communicate with Gmail's SMTP server.
I have been having the SAME problem with ALL my Gmail accounts with Mail.app - It is very annoying, especially when you have clients and other important email to respond to. So you're definitely NOT alone in this department.
Might have to go back to Thunderbird or something until this gets fixed, which is going to really suck because I have 5000+ emails along with all my Email Folders in Mail not too mention the Rules I have had setup for years!
AND with the RSS Feeds NOT working in BOTH Mail and Safari! That was a HUGE MISTAKE and defintely a STEP BACKWARDS on whoever's idea that was for sure!

Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install. Once I wrote my password, and for now on, everytime I start the session, another window advise me that "Java SE 6" is missing, due that, the computer can't run some "CS5Service Manager". If I try to install it, the download ends with an error. If finally, you skip the istallation, you arrive to the dock, but the menu bar at the top of the screen doesn't show up.
In addition, my trackpad doesn't works either. I can move the arrow but i can't click anywhere, probably because the option of clicking by touching is disabeled and I can't performance a regular click.
I'll be very glad if someone know what the heck is happening with my computer. Anyway, I'm going to the genius bar next Saturday. Thx!

We're sorry.

Please return to the Apple Support homepage.
Sigh.

How do I partition my MacBook Pro so I can keep Snow Leopard and also install Mountain Lion?

How do I partition my MacBook Pro so I can keep Snow Leopard and also install Mountain Lion?
I want to install the latest OS, but I already know that I will lose a lot of my software unless I can partition the hard drive and have two "bootable" drives.
How do I retain everything I have, partition the drive, then reloa the software I own according to which OS it will work under?

I do not currently own OS X ML.
I am currently running OS X (10.6.8 Snow Leopard) on my MacBook Pro. It has a 2.8GHz Intel Core 2 Duo Processor. I want to upgrade to Mountain Lion, but many of my software titles will not operate with ML and I cannot afford to replace some of them (Adobe Creative Suite, for e.g.)
After I back-up my HD and then partition the HD, how do I use the back-up to reinstall what I want to the SL partition, and then place the rest on the ML partition.
I have not done what you want to do, so can only offer some general thoughts in support. Take value from the following where you can. No guarantees.
If it was me, I would use a disk clone utility (e.g. Carbon Copy Cloner) to image the existing Snow Leopard disk to an external drive. Then verify that the external drive would boot and run Snow Leopard normally.
I would then purchase and download the Mountain Lion upgrade installer, but not run it. Use Lion Diskmaker to make a bootable USB stick, and perform a clean install of Mountain Lion, replacing the Snow Leopard on your MBP. This way, you make absolutely certain that no third-party drivers or other SL cruft remains to make Mountain Lion unstable. Update to latest ML point release. Fix permissions. Let TimeMachine make a full backup of your ML installation to a different external drive. Then turn of Time Machine.
In Disk Utility, use the + sign at the bottom of the ML partition to add another GUID, HFS+ Journaled partition for Snow Leopard. Resize to taste. Name it differently from your ML partition. Exhale.
Now ideally, you would like to reverse the external clone and put it back into the new SL partition. Then fix permissions. And demonstrate that you can boot into individually stable OS X installations. This would save you alot of work. Resist copying your home directory into ML just yet.
If you cannot successfully achieve the preceding paragraph, you will be faced with a full SL and application reinstall.
The ~/Library contents for SL and ML are sufficiently different that you do not want to mix them. You may want to salvage Safari bookmarks.plist. And, ML created folders in the home directory may have different permissions or ACL settings than in SL. So, my rule of thumb would be to copy folders that you created in SL, and only the contents of matching named OS created folders such as Music, Pictures, Downloads, etc.
For each operating system, you probably want the Time Machine settings to exclude the opposite OS X partition. If you use the same host name in Sharing prefs, then you will mix SL and ML backups on the same Time Machine back up drive. If you use different host names, they will be distinct folders in the Time Machine backups.backupdb and allow discrete restores per host. You may also want to gag Spotlight from indexing the opposite OS X partition.

Ethernet connection issues after installing Mountain Lion

After installing Mountain Lion I can't get my iMac to connect by ethernet. It says that no cable is connected. The cable/connection is fine. When I plug in my MacBook Pro running Lion, the ethernet connects just fine.

same exact problem. in fact, my iMac24 (2009) worked flawlessly until I installed the latest update to Mountain Lion. I then checked my MBAir (2011) and it too has a problem when using the USB/Ethernet adapter. Neither can get an ethernet connection. I deleted my network preferences and rebooted my machine, played around with my Ethernet switch and even reboot my gateway/router. I've never had to do any of this to my network until Mountain Lion. Wireless is the only thing that continues to work on both machines.

My macbook pro is very slow after installing mountain lion

my macbook pro is very slow after installing mountain lion? Is anyone else having this issue?

If you don't use an SSD and bump your RAM up to 8 Gb's you may experience slow speeds, but I noticed slow speeds with your general configuration in SL.
one thing you should consider right now is, Spotlight is Reindexing your hard drive, that takes time and resources, (resources which you don't necessarily have to spare).
If you continue feeling like your performance is slow, you have a few options with this computer (I have the same one).
the express card slot can house a wintec SSD drive. That little door on the side of your machine is pure gold for a really quick solution for speeding up your machine. I have one in mine right now i'm using as a scratch disk for CS6 but I used to boot from it, and the speed boost was out of this world.
You could take out the internal HDD and put in a new SSD (I have a Vertex 4 from OCZ) it is completely over kill but my experience is pretty fast and I keep up with the later MBP models colleagues have.
There are some other options for you like taking out the optical drive (however I don't know if I'm supposed to talk about that here). Google Data Doubler.
You need to also set it to always use the 9600 chipset, this will increase performance a lot too. to do this go to system preferences>energy saver>Better Performance. This switches the video card to the better one and makes a world of difference.
Lastly, your RAM. after an EFI Firmware update, our computer support up to 8GBs of RAM. Do it!
