If I upgrade to Mavericks..

Will I be able to downgrade if I change my mind? If after using it I realize it doesn't work for me, will there be a window of time that I can downgrade? Because I hate my iPhone now so much, my trust is gone. I am being forced to use something I hate. How do I know this won't happen again and again? I don't want to be held hostage to any system if the one I bought worked fine.

There is no easy downgrade route except to make an external clone of your existing Mountain Lion system, using Carbon Copy Cloner or such. This is a good backup strategy anyway.
Note: Mende1 suggests Time Machine, which is also good and keeps past versions. But you cannot boot into it, to make disk checks or do a clean install, should you want to.
Both methods have their place.

My Apple Mini Display Port/HDMI adapter is not working after upgrading to Maverick?

I am using my 13" Macbook Pro Purchased July 2013 on my 42" Samsung TV. I route through a HDMI adapter (purchased from Apple) to do my presentations. As a note my setup has been working great for the last year. Immediately following the upgrade to Maverick my Samsung displays "No Signal" and changes state "Check Signal Cable" when the cable is disconnected. Obviously there is some type of signal but it is not recognized. I tried working with Apple support and they said that the adapter I was using must not be an Apple product. I investigated fully thinking I may have possibly bought the wrong item, after much research I have exactly the same thing sold on the Apple store online and I even went to 3 Apple stores locally to see if there was possibly another adapter that I should have purchased, but it was exactly the same thing I purchased originally. Help me fix the problem or please provide details on how to go back in operating systems to prior to Maverick (and not lose any of my data), this upgrade was a huge mistake way to many problems and not the quality that I am used to from Apple.

Had a similar problem, but the answer is not a good one.
You are going to have to wait until Apple fix this as some 3rd party monitors are not supported by this update.
So you can:
Go back to 10.6.7
Wait for Lion
or
Use Onxy to clear up your computer and it may link to it again.
I deleted some preference files, which when they rebuilt themselves after a restart did the trick.
It worked for me, let me know how you get on?

I can't update my iPhoto after upgrading to Maverick

I just upgraded to Mavericks and ever since, my iPhoto (v. 9.2) will not work. It has a grey circle with a line through it over the application. I do see in my app store I have an update for iPhoto 11, but when I try to upgrade it and enter my apple ID, I get this error message. I only have this one apple ID and password, so I have no idea why it is saying this. I am so scared I've lost my photos!!!
Error message reads:
Update Unavailable with this Apple ID:
This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled.
I do not understand this or what to do. I have not ever tried to purchase this previously.
PLEASE HELP!!

You must log into th eApp store using the Apple ID that was used to set up the computer
If that is not working then you must contact App store support - link is on the right of the app store windw

After upgrading to Mavericks I cannot update iPhoto and iMovie. Why?

Just got my first Mac, an iMac. I upgraded to Maverick and once done I find there are updates available for iPhoto and iMovie. First I have tried to register "accept" the two apps. Nothing happens. Then I try to update them and get the answer that these apps was installed with another Apple ID. The thing is that I don't have any other Apple ID and noone else has touched my iMac. I have tried to reinstall Maverick three times now but end up with the same result. Anyone who has any clue or have experienced the same problem?

Open System Preferences > Users & Groups then select the Password tab.
Make sure you see the correct Apple ID.
If not, click Change.
Make sure you are logged into your admin account before updating apps.
Reinstalling Mavericks requires using OS X Recovery but there's no reason to reinstall Mavericks just to update your apps.

Open the Mac App Store application and see if iPhoto is under your "Purchases" tab.

the problem I have since I upgraded to Mavericks version 10.9.1
The problem appears only with Mail not with other programs, not even with my browser.
When I try to zoom the text of an e-mail I received or sent , I can no longer use the keys Command + to enlarge the text, although I can reduce it with Command -.
As I have a problem with my eyes, This is a serious matter for me.
When I write an e-mail, if I select text and press Command +, it just displaces the text to the right.
Now, my husband has a USB keyboard. If he connects it to my computer, his regular Command + does not work either, but he uses the extended keyboard, then it works. Unfortunately, he needs it for a musical application which does not work with a wireless keyboard.

Firefox 3.6.4 and 3.6.6 use a process called, "plugin-container.exe" which was using up most of my CPU when I opened up multiple tabs that contained Adobe Flash files, and caused Firefox to lock up.
My solution was to use Firefox 3.5.10 which you can get from the Mozilla website at [http://www.mozilla.com/en-US/firefox/all-older.html]
I am using Adobe Flash 10.1.53.64 without any problem in this version of Firefox. Check the release notes, I believe it contains all the latest security fixes in "Firefox 3.6.4".
Hopefully, they will fix Firefox 3.6 in the next version (e.g. Firefox 3.6.7), until then you should probably use "Firefox 3.5.10".

After an upgrade to Mavericks - my Video Camera is no longer recognized by the system (JVC Everio HD video camera)

I just upgraded to Mavericks (up from Mountain Lion) last week. Today, I tried to upload movies to my MacBook Pro, and it no longer 'sees' the camera when plugged into the USB port. I have tired iMovie, iPhoto, and also direct access, via the hard drive. Nothing works. I have even restarted the computer with the camera plugged in and it is still not being recognized, and I cannot get the movies 'out' of the camera. I have never had a problem before , In fact I loaded movies last week, just by pluggin it into the USB.
Are there ANY suggestions on how or what to do for it to start to pick up on the fact that my video camera is indeed plugged in and has movies that can be imported?
Thanks!

Just upgraded to Mavericks. How do I get my Epson Workforce 360 scanner to work again?

Just upgraded to Mavericks. How do I get my Epson Workforce 360 scanner to work again?

Try Image Capture, which comes with your Mac. It should be in the Applications folder, or if not, try the Applications/Utilities folder. It should automatically find the right Epson driver for your scanner.
Also, I'm guessing you have Epson 630 rather than 360. If so, see this from Epson Website.
The latest printer and scanner drivers for this product are available from Apple's Software Update. Here's how to get them:
Do one of the following:
USB
Connect your product to your Mac using a USB cable and make sure the product is turned on.
Wireless
Connect your product to your router wirelessly and make sure the product is turned on.
Note: You'll need to use the product's control panel to establish the connection to your router.
Ethernet
Connect your product to your Mac using an Ethernet cable and make sure the product is turned on.
Select the menu on your Mac, then Software Update.
Do one of the following:
If you see an update from Epson, select UPDATE to install it.
Note: Apple Software Update may find multiple updates for your system. You may choose to install all or some of the updates.If an update is not available, you're done. You already have the latest drivers from Apple.
Note: You can also use EPSON Scan if it's available for your product. To get it, go to the Epson main support page, select your product, then select Drivers & Downloads. Select Drivers, then Scanner Driver and EPSON Scan Utility.
For more information on scanning in OS X, see our Image Capture FAQ.

Can not find a library in Aperture after upgrading to Mavericks?

I upgraded my Aperture to 3.5 on Mavericks. Since I have updated my Aperture, I cannot open my second Library "Aperture Library"
This is what it happens:
I can not find my "Aperture Library" photos, and when I try to switch between the library (File>Switch Libaries>"Aperture Library" this comes up:
When I click on relaunch:Then when I click on "Aperture Library" and press chose, a 3 second process occurs and Aperture returns back to where it was when it was opened. The "Aperture Library" doesn't appear anywhere.
When I go to Altinoz (My Mac) > Pictures > Aperture Library:
When I try to open the Aperture Library folder in My Mac > Pictures > Aperture Library
Do you want to import this library to Aperture (which was already in the old verison of Aperture)
An error comes up:
The library could not be imported because it is from an out of date version of Aperture 3. Please upgrade the library to the latest version of Aperture 3 and try again.
I would really appreciate your help on helping me find "Aperture Library" Photos I have, since the upgrading to Mavericks really made annoying problems to me.

It seems to me that you need Aperture 3.2.4 to open your library.
If you have it then do the following:
Uninstall Aperture 3.5
Install Aperture 3.2.4
Start Aperture and verify that you can access your library
Update to Aperture 3.4.5
Start Aperture and verify that you can access your library
At the end update to Aperture 3.5 and upgrade your library
If you don't have the older versions, maybe try to open the library in iPhoto. Does that work?

After upgrading to mavericks, all my downloaded apps crash

Hey guys-
I upgraded to mavericks 2 days ago and love the os and the look and feel. the thing is, i have a bunch of downloaded apps like openoffice and parallels desktop and after the appstore upgrade, the apps just plain freeze up. Any ideas on how to fix this issue? Help would be greatly appreciated as i need to use some apps for work as well.

Open Office works fine on Mavericks on 4 machines of mine, 2 mac mini, macbook pro, and macbook Air.
So, open office DOES work in Mavericks.
repair disk, and last resort reinstall Maverciks
http://support.apple.com/kb/HT1452
Reset SMC
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

Mail Signatures, Folder Organization, Notification and Attachments not working the same since upgrade to Mavericks

Hi All,
Normally very quick to do so, I’ve been hesitant to upgrade to Mavericks based on so many issues being reported with Mail + Gmail.
Previously Apple released a fix for these issues and I still waited a while. This weekend I upgraded to Mavericks and Mail is definitely not working as I’d expect it.
Some of the things I notice include:
1) My saved mail folders, previously in alphabetical order, are now in reverse alphabetical order and dragging them to be in a different order has no effect
2) Previously when I clicked on a message and pressed Message > Remove Attachments the message would reappear in my inbox within a second or two, without the attachment. Now, the message simply disappears.
3) The little red icon no longer appears in the dock when a new message arrives
4) For my various accounts, signatures do not appear/disappear as I select a different From account (each of my accounts has different signatures).
Does anyone have thoughts on any of these items?
Thanks,

Not an answer, but a repeat ...
I too have problem (2) -- Remove Attachment now makes the email in question disappear (in fact moving it to Archive).
Help would be appreciated.

Running mountain lion os 10.8.5 on mac book pro mid 2012 build. If I upgrade to Mavericks will MS Office programs still work?

I am running mountain lion os 10.8.5 on mac book pro mid 2012 build. If I upgrade to Mavericks will MS Office programs still work? There does not appear to be an updated version of MS Office for Mac past 2011 that I bought last year and am using now. Thoughts? Suggestions?
Thanks.

Office 2008 and 2011 will run on Mavericks, but you may not be able to get the installer for it at this time.

I have been trying to import VHS video into iMovie via a Hollywood Dazzle bridge. Did not have trouble until I upgraded to mavericks. I have a mac book pro, 10.9.1, iMovie 10.0.2. Says it is recording, but when I go to check, it says the file is empty.

I have been trying import VHS video into iMovie via a Hollywood Dazzle bridge. I have been successful doing this in the past, but now it is not working. I have a mac book pro, 10.9.1, (mavericks), iMovie 10.0.2. Everything in iMovie looks like it is working. It reads "recording" in the upper left hand corner of the pane while the video is playing. When I stop the process to check on my clip it says that the file is empty. The only thing that has changed since I did it successfully is that I upgraded to mavericks from whatever I had previously. My system is about one year old. Any suggestions?

Hey, Clinton,
     Thanks for your help! I was able to go to iMovie 9.0.9 and import video. I was still curious as to why it didn't work in version 10.0.2, so I contacted Apple tech support. They were't sure at first as to why it wouldn't work, so they had me delete iMovie 10.0.2 and then re-install it just to see if something had gone wrong when it upgraded. That didn't change anything. In the end, they determined that 10.0.2 doesn't support the Hollywood Dazzle DV bridge. But I have a workaround path from them that I will share so that it's possible to import to 9.0.9, then move it to 10.0.2.
     1. Open iMovie 9 (finder/applications/iMovie 9.0.9
     2. Import from Dazzle Bridge to iMovie 9, note which event you are importing the clips into
     3. Close iMovie 9
     4. Open iMovie 10 (probably in the dock)
     5. File/Import Media...navigate to home(this was my name, on the left side of iMovie, under Favorites)/Movies/iMovie events. Find the event folder that contains your Dazzle clips (tip-try sorting by date modified to look at recent events.)
     6. Select the clips and import. Click the blue "Import Selected" button on the bottom right.
You may get a message that some files cannot be imported. Click continue import. It's a little glitchy. It imports your clip, and also makes a copy of it, too. On the copy, the audio is normal, but the video is choppy. In any case, you would delete the copy, anyway.
Hope this additional information helps somebody else. Thanks again, Clinton for helping me!

HT201364 How do I get more free space in order to upgrade to Mavericks OS. I only have 1gb available and I need 2

How do I get more memory so I can upgrade to Mavericks OS? It is telling me I need 2GB and I only have 1GB available.

You need to buy and install more RAM. Use a source such as OWC or Crucial.
