CMD+Tab Issues In Mountain Lion (consolidated)

I've seen CMD+Tab Mountain Lion issues myself and some others have posted online, so I'm consolidating them here:
CMD+Tab fails to show all running apps that are running (includes native OS apps such as iPhoto, Mail, etc.)
Pressing CMD+Tab does nothing (no pop-up), although the cursor does appear as if the command is partially being processed. (window prepping?)
CMD+Tabbing OUT of a full-screen application takes you to desktop, but then hides app icon from dock and CMD+Tab menu won't appear again... effectively leaving you stuck outside of the full-screen app (SC2). Only option is to go to activity monitor and kill process.
Interesting Side Note: I also use Alfred (CMD+Spacebar) for a shortcut/index app, and whenever CMD+Tab fails, Alfred also fails and I'm forced to manually used Spotlight to open apps. This suggests something could be tying up the CMD button and preventing it from executing combination key presses... maybe?
FIXES: The only solutions so far involve killing the processes of the perpetrating apps, i.e. finder, dock and any full-screen apps which caused the problem. Even doing so, the problem will manifest itself once again within a few hours.
Cheers!

I haven't tried experimenting with a guest user account as I solely use my admin account, but I'll play around a bit tonight. I only posted as it's manifested itself multiple times on my machine, no matter whether I sleep my computer, power nap it, restart it completely, etc. and it seems as though others have been experiencing similar issues:
https://discussions.apple.com/message/19236413#19236413
https://discussions.apple.com/message/19171533#19171533
https://discussions.apple.com/message/19106906#19106906
https://discussions.apple.com/message/19137798#19137798
It seems as though the problem may lie more with applications running but not displaying as if they're running, i.e. won't appear on dock, or if it's a native app, icon won't have indicator light, and also not available in cmd+tab menu.
Certainly odd behavior.

Tap to click not working properly in Mountain Lion. How do I get apple to fix this major issue with mountain lion?

The tap to click does not work with mountain lion as it did before the mountain lion install. I purchased a brand new imac in August of 2011 and got a wireless keyboard and selected the wireless trackpad instead of a mouse. The trackpad worked wonderful pre upgrade with tap to click. Now after the install of the newest beast, I have to actually press the trackpad rather than a slight tap. I have carpel tunnel and this is causing great stress upon my hand. How do I get apple to fix this major issue with mountain lion?

Perhaps, I was not clear enough.
I have an imac purchased in Aug. 2011 which came with Lion 10.6 (two uprades before mountain lion)
Recently, I just purchased a macbook pro retina with Mountain Lion
On my imac, my settings allowed me to "tap to click" everything EXCEPT the initial log in at the star up of my imac, again running Lion 10.6
On my macbook pro retina which has Mountain Lion, I set up the "tap to click" option, but notice that a "hard" click was neccessary when trying to click things. I thought this was a macbook thing (my first one) so I went and upgraded my imac to Mountain LIon, BIG MISTAKE! Now both my imac AND my macbook only have limited "tap to click" options. Before mountain lion I could "tap" to highlight and select text, tap and drag, and many other thiings that Mountain Lion has disabled.
I am truly surprised that no one has noticed this MAJOR issue.
Is there a way to uninstall this update, similar to how on a PC you can go back to a restore point.
On another note even the way PREVIEW has changed is less user friendly, there used to be icons on the bottom right corner of the screen, now I have to double tap and select the option I would like to switch between contacts and thumbnails. This is really annoying and is causing me time when reviewing files.
Just in case anyone was wondering, I did go to system preferences -> trackpad -> select tap to click
In fact almost all of the trackpad functions have been selected.

Has Apple done anything to address the issue of Mountain Lion's inability to support Epson printers? I have a Stylus Photo RX620 that now is useless. I am not a computer geek so would rather not try to do an uninstall of Mt. Lion and go back to S.Leopard

Have you tried to open System Preferences, then Print & Scan and then try to Add + a printer?
I have an Epson RX580 and am using OS X 10.8.2 and it is working as a (Bonjour) printer. My Epson RX580 is plugged into my AirPort Extreme and I can print over my wireless network to the RX580. However, I do not see any Scan options with this setup.
Anyone know anything about getting the scanning portion of the RX580 to work over the network like the printing function does with my Airport Extreme? Or can I not "share" a scanner over the USB port on the Airport Extreme? I know, kind on topic/off topic - but I think it fits under OS questions better.
Thanks for your advice!

Start up Issues with Mountain Lion?

Having start up issues with Mountain Lion. Gray Screen and nothing happens.

If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Safe mode is slower than normal, and some things won’t work at all. Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the startup volume is on a software RAID, you can’t boot in safe mode. If you're able to boot, launch the Console application in any of the following ways: ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. ☞ Open LaunchPad. Click Utilities, then Console in the icon grid. Select the most recent panic log under System Diagnostic Reports. Post the entire contents — the text, please, not a screenshot. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post shutdownStall, spin, or hang reports.

TS1550 Time Machine issue with Mountain Lion. Can you help?

I have an Iomega Mac Companion used as an external backup drive for my Imac running Mountain Lion. After launching Time Machine, I got an error message that said the backup couldn't' be completed because an error occurred while creating the backup folder. I rebooted and everything was fine for 24 hours. Since then, I get the same error message even after another reboot. In Time Machine preferences it says "oldest backup none" and "latest backup none."
Any suggestions?
GR

Finally have it solved!! Sort of... I spoke with Mac support on two occasions and they were extremely helpful. Thought the issue was with the firewire 800 connection. Switched to a USB connection and everything worked great...for about 24 hours. Then had the same error messages. Chatted with Iomega tech support and they finally admitted that there are known issues with Mountain Lion, there is no work around and they have no intention of making it compatible with 10.8.
I'm returning the drive today. Thanks for your help and suggestions. Suggestions for a decent back up hard drive that will work with Mountain Lion?

Panasonic HDC-TM900 issues with Mountain Lion.. Not compatible??

Hi, I can't see any of my video files I recorded onto my camcorder once plugged in via USB. I have a Panasonic HDC-TM900. It work fine before I updated to Mountain Lion.
When I plug my HDC-TM900 camcorder into my MacBook Pro, all the files on the camera Memory and SD card could be seen. All I did then was copy and paste the MTS files from either the Camera Memory or SD card to my desktop and convert them in iSkySoft. ( this all worked fine before I updated to Mountain Lion.
I tried plugging in the Panasonic into my iMac and MacBook this still run the older OS and all the files can be seen with no problem.
So I have concluded that it could only my an issue with Mountain Lion that it does not see or pickup certain files off my Panasonic camcorder
Can someone help ? I am very desperate to find answers.

I can't tell you why, but I can tell you that Apple published the list of supported hardware on its website quite a while ago. The oldest MacBook Pro model that supports Mountain Lion is the Mid/Late 2007 model. You have the late 2006 model.
Details are (and have been) here:

Strange Wi-Fi issue in Mountain Lion

Hello Mountain Lion Gurus/Users/All,
Just yesterday I upgraded my 2009-mid-MacBook Pro to Mountain Lion (from Lion)
I have this strange issue.
I turn on my Wi-F
Selected my home network from the list of all the networks Mac could find. (Actually this is the network I regularly use on all my devices.)
It gets connected to my home network over Wi-Fi for 6 to 7 seconds. (I am able to browse pages, as a test, in these 6 to 7 seconds).
Suddenly message pops up saying "Connection Timeout. Could not connect to network." Where as, I am able to browse over the same network from other devices like my iPod Touch, Android :@ Device etc.
Please help me.
Chandra

Chandra,
Some people have found that setting a network location prevents this kind of problem.
In System Preferences, choose Network. Then Edit Location, the + sign and use any name for the location. Then select the location in the Network preferences pane. If you haven't already, joint the wifi network.
You should also check that you haven't inadvertently messed up your settings in the advanced portion of the preferences. While you're in there, click the button to renew your DHCP lease (in the TCP/IP tab).

Issues with mountain lion upgrade

Has anyone had any issues when upgrading from snow leopard to mountain lion?
I upgraded on Sunday and since have had some issues with access to the Internet. The only way I can get it is by switching off wifi and back on again.
This is happening on both admin account and my sons profile. Though interestingly when I try and access the parental control panel for his account, I get some system errors.
Any help or support would be appreciated.

I also upgraded from Snow to Mountian. I can bring up google search results but can't load any web pages. My Mac Pro was working great with Snow never had any issues with internet. Saw a post with a solution of disabling auto proxy but that doesnt work. The only way I can load a web page is if I restart my Mac open up Safari then I can usually bring up one web page and then I can not load any more. I cant connect to the App store either. I dont know how I will be able to download a patch from Apple now.

Strange Application Issues after Mountain Lion Upgrade!

I'm having, what I believe to be, strange issues with a clean install of Mountain Lion from 10.6.8
It's for my boss' computer at work so I can't afford to have it down for very long at a time. It's hard to pinpoint the issue(s).
Computer:
Mac Pro - Early 2009
OS X 10.8.3
2 x 2.6 GHz Quad-Core Intel Xeon
32 GB 1066 MHz DDR3
The startup disk is 4x2TB RAID 5 using Apple RAID card (Firmware version: E-1.3.2.0; Hardware Revision: 2.00; Driver version: 124
The following is what happened/is happening:
1. (Tuesday)
Created a bootable backup of system drive using Disk Utility
Performed a Clean install
Used migration assistant to copy over applications from backup
Downloaded (from Amazon) and installed Microsoft Office 2011
Imported Addresses (including imported Previous Recipients that were imported into Contacts before exporting on old system)
Setup email & copied over mailboxes from backup
Moved all files back onto the system (User folders)
Everything worked fine from Wednesday - Sunday.
Problems reported to me (Sunday)
"Chinese characters" on save dialogue box in Microsoft Excel
Mail crashed while dragging a photo from safari to it
After a restart, Mail, all Microsoft Office apps, and Final Cut Pro wouldn't open.
Tried to reset preference files, but nothing worked.
2. (Monday night)
Performed another Clean Install
Migrated Applications
Transferred mailboxes (not old emails at this time)
Imported same group of addresses as before into Contacts
Installed Microsoft Office
Moved user data back
Transferred old email mailboxes (Tuesday afternoon)
Everything worked fine Tuesday - Thursday early morning)
Problems reported to me (Thursday morning)
When typing in an email address to send an email, it didn't autofill. Mail crashed.
Mail wouldn't open. Different from last, this time it said the ~/Library/Mail folder was moved. I checked and the folder was there with everything in it fine.
The Microsoft applications that were open at the time of the Mail crash still worked, but others wouldn't open. After closing the open applications then they wouldn't open back up (same as before)
Final Cut Pro opened fine.
Fixed Mail by deleting the ~/Library/Containers/com.apple.mail folder.
Later found out that though Final Cut would open it would crash when loading a project and that Quicklook wouldn't work for quicktime files across the network & codecs were missing (this could have been cause by me when trying to test problems).
3. (Sunday)
Restored from a different bootable backup I made after 2nd clean install and migrated applications.
Repaired Permissions using Disk Utility
Moved over Mail data
Copied over user data
*Didn't import the addresses
Checked to make sure all the fonts were validated and no duplicates
Everything worked fine after install and through Monday.
Problems to me (Tuesday morning)
Microsoft Office disappeared completely from the computer. No folder in Applications or dock icons.
Slower to connect to network files
Re-installed Microsoft Office to keep work progress going.
What would be causing this peculiarity? It works after I fix it and for a little afterwards but then strange things happen.
Would repairing disk permissions on bootable backup (of 10.6.8) before using migration assistant help?
What is the best way to track down what is causing these issues?
Thanks!

I suggest that the best way to upgrade from 10.6.8 to Mountain Lion is one of the following:
(1) Simply perform an upgrade install. This is in fact Apple's recommended approach. I am not sure why you have not yet tried that. I have done this myself successfully.
(2) Make a backup of the working 10.6.8 system; better yet is to make two complete backups, one being a "clone," the other being a Time Machine backup. Use of two different methods gives you options should something go wrong. Then erase the original disk and install Mountain Lion, and on the first boot up run Setup Assistant (which is better than Migration Assistant) and transfer over EVERYTHING, including user accounts, settings, applications. I have also used this approach, also successfully.
You did neither (1) nor (2), but seem to have done some sort of hybrid by transfering applications and then manually moving over some mail files and moving over some user files. I don't think this is a recommended approach. It can result in permissions issues, which can cause things to "disappear" or otherwise behavior oddly.
I do not understand how your use of a RAID setup and a RAID card might affect any procedures which otherwise might work smoothly. Are you 100% certain that your RAID hardware and firmware are compatible with Mountain Lion?
Assuming that the RAID is not the issue and it behaves to the OS just like a normal disk, I would try the full disk erase and install of Mountain Lion followed by a Setup Assistant on first boot up to move over everything from your clone backup.
If this does not work, then I would erase and restore back from your clone, so you get your 10.6.8 system working again. Then I would try a simple upgrade install of Mountain Lion.
If that fails, then I would erase and install Mountain Lion with one new administrative user created who has a different user name than the person whose stuff you need to restore. Then with that new administrative user I would make sure the RAID is all up and running. Then I would use Migration Assistant to migrate over users only and would reinstall all software from scratch. If that is not to your liking, I'd as a less desirable alternative use Migration Assistant to migrate over everything, applications and users. You will have that new, extra administrative user as well as the original user(s), but that should cause no harm.

Illustrator cs5 selecting issue in mountain lion

I'm having a strange issue using illustrator cs5 after updating to mountain lion. I have a line of text that I rotated and copied several times so it resembles an asterisc shape * (3 lines of type fanned out over a central point). When I select 1 line of type, 2 or more lines are selecting. It happens even if I try to click in an empty area of the file (white space). The kicker is that it even happens in outline view (even in the white space). Any help is appreciated.
Thanks

Not sure what is happening, but a workaround might be to put each line of type on its own layer, then lock and/or hide layers you don't want to select.

I am having issue updating Mountain Lion on my Macbook Pro.

I really am having issues updateing. The updates are iPhoto, Macbook Pro firmware, and Thunderbolt update. When ever i download and install them and then restart they just appear again that i need to redownload them

Exactly as John Galt stated there is no support for Mountain Lion, being pre-release software. I personally run Mountain Lion on a virtual machine through VMware Fusion 4.

Trackpad issues after mountain lion install

Since my Mountain Lion install, the trackpad on my 15" MBP will track, but won't select anything. Hot corners aren't working, the dock won't appear, etc. Anyone have any suggestions?

Got similar issues, no notifications and no switching between full screen apps (4fingerswipe). Some swipe features work, no secondary click in bottsom corners...Trackpad operational under Mountain Lion a total nuisance compared to Snow Leopard...PLease Apple, show some respect again to your faithfull customers and show some response!

Color issues in Mountain Lion with Acrobat Pro

I'm not sure I'm in the right forum, but here it goes.
Since upgrading my OS to Mountain Lion, I've noticed when viewing PDFs output from InDesign 5.5 that once in Acrobat Pro the colors look muted and inaccurate. I never saw this in Snow Leopard, hence my posting. Color in InDesign, Illustrator and Photoshop CS5.5 seem just fine, it's only when a PDF is viewed in Acrobat that I see this muted color issue.
What I'm concerned with is are these problems when viewing only, or is the PDF color range itself screwed up? I do prepress work and am using an Eizo CG241 display, CS5.5 and Acrobat Pro 10.1.4.
Thanks!

If you are using a calibrated display, the calibration software should set your Displays>Color profile for you. Mine is set to "PA271W 0610738UA 2012-11-14 14-57", which is the name of the profile created by the calibration software. This is where color temperature, gamma, and color corrections are stored (in my case for prepress work at 5000K and 1.8 gamma).
Sorry about this long-winded posting, but I think the last few paragraphs may help make some progress, and I must first digress to get to them...
Control of color profiles embedded in my PDF files is done in Adobe Creative Suite (verson 6 at this time). I use Bridge to synchronize the suite. North American Web/Internet is for files going to the web and I apply sRGB to those files when opening them (if they aren't already sRGB). North American Prepress 2 is for files going to a printing press, and I apply Adobe RGB to files when opening them (if they aren't already Adobe RGB).
Files for the web are saved using Photoshop's "Save for Web..." command, which is set to sRGB and uses the Document Profile for a preview.
Files for print are converted to CMYK and placed in InDesign or Illustrator, where they are saved as PDF/X-1a files, which are CMYK and those values are preserved (not color managed). I should note that before that point, during client proofs, the files are placed as Adobe RGB. They are replaced by CMYK images before making a PDF/X-1a file for the printing press. Either way, the files display correctly and identically (except for any color gamut differences) regardless of color mode or application. (This is color management working correctly.) Except for Acrobat and Reader.
Until CS6, all PDF files would be displayed by Acrobat identically to how they appeared in the originating application (Photoshop, Illustrator, InDesign). Now all PDF files are darker, more drab, and shifted slightly toward blue.
Here's the weird thing. No matter what I do, even if I start with an sRGB file and save it as a Photoshop PDF using the Save for Web command, so it has been sRGB throughout the process, when the PDF file is viewed in Acrobat or Reader it is darker, more drab, and shifted slightly toward blue.
My first hypothesis was that Acrobat and Reader were applying sRGB to everything. But that appears to be wrong. Now I'm thinking that it's my calibrated display profile that is being ignored. And since it is calibrated for 5000K and 1.8 gamma, that is what explains the big shift in darkness, vividness, and color. It may be that the display profile, not the embedded color profile, is all that matters!
If so, a good experiment would be to calibrate one of your displays for 5000K and 1.8 gamma. If Acrobat and Reader are ignoring the display profile, you should see a very obvious difference in displayed PDF files compared to displays using 6500K and 2.2 gamma (which is just about everyone these days, except for publishing professionals who do exacting print work).
Sheesh!

Issue with Mountain Lion Account

So heres my problem,
When Mountain Lion came out earlier this year I purchased it, but since I didnt have a credit card I just downloaded it off a friends account. Ever since I have downloaded it I have been having issues with mail accounts. It always comes up with his name and email adress when ever I add a new account (details are already saved when you add a new mail). I couldnt stand it any longer so I made my own Apple ID and redownloaded Mountain Lion off my account it since I have reccently got a credit card. Yet the still problem occurs even after re-installing mountain lion off my own account.
I have deleted all mailing accounts and added them again but still the same thing happens. Do not have a clue why this happens because the Mountain Lion I am running now was bought off my own account. It really annoys me and do not want some preset details popping up everytime I want to add something to my computer.
Hope this makes sense to you all.

This is because while you've re-installed the system, you've preserved the user account.You need to do a "clean" install meaning a reformat and install. If the Mac orginally shipped with Lion or ML you can redownload via Recovery Partition but if the Mac shipped with Leopard 10.5.x or Snow Leopard 10.6.x then you need the OEM discs that shipped with it. You can call Apple and they will send you the discs for a nominal charge.
