Problems with OSX Mavericks - How do I return to previous operating system?

I installed OS X Mavericks on my iMac. Now Safari, Mail, iPhoto, basically all software, hangs up as soon as it is opened. Nothing runs.
Also I have this constant request for keychain password which I haven't set up. I tried the fix I found online, but as soon as I click on "mail preferences" Mail hangs up and I have to force quit the program.
I have re-installed this software 3 times now. It has not functioned properly yet. Thank goodness Firefox still works.
Any solutions out there?

Apple doesn't seem to know how to "fix what's wrong".
I spent about an hour yesterday with Apple Tech Support. No solution.
I had a mbp running Mountain Lion and iPhoto 8.1.2. Perfect harmony.,
I purchased a new mbp from Apple, running Mavericks. It has iPhoto 9.5.1 on it.
When I started up iPhoto, it told me that my previous iPhoto library was not compatible and that I needed to "upgrade my iPhoto database"
I click on that link, and iPhoto stops responding.
Tech support walked me through various attempts at solving this problem, but all attempts failed.
After about an hour, neither the original tech nor the supervisor who took over had figured out what to do.
They told me that, as a last resort, they could save the photos in my old library and be able to use them with iPhoto 9.5.1, but I would lose all the organization (albums, folders). How is that acceptable, Apple? It's a big deal to me. They kept telling me that this was a very unusual case, but if you google "mavericks iphoto problem" you'll see lots of other people having Mavericks/iPhoto issues. They told me that I had a corrupted iPhoto database, but that database works just fine in Mountain Lion with iPhoto 8.1.2.
Supervisor is supposed to call me Sunday afternoon to follow up on this ....

Welcome to Apple Support Communities.
It sounds like your iPhone is in recovery mode and you’re concerned about restoring it to factory settings because you don’t want to lose any data. The first article linked below provides a lot of great information about restoring an iOS devices to factory settings, including how to restore from any backups that you may have created with iTunes.

Also, if you want more information about recovery mode, take a look at the article linked below.

Webmail problems with osx mavericks

hi,
since upgrading to mavericks i have problems using my work microsoft webmail on both safari and chrome – on chrome the pop-up window to add attachments no longer works; on safari it barely works (i have to open the attachment pop up twice before i can upload an attachment), where it also keeps crashing. outlook webmail light is not an option...i just want to get my outlook webmail to how it was before with mountain lion!
please can anyone assist?

We've been expereincing a similar thing:
first attempt brings up a standard looking OS X file choosing dialog box which does nothing after you pick a file
the 2nd attempt brings up the expected OWA attachment chooser dialog box and we can then attach normally
We've told our users to switch to Firefox/Chrome (or enjoy attaching things twice).
Have you seen any solutions?

A sign in problem with OSX Mavericks

Every time I start the computer I have to sign in again. I do not need this protection and how can I change this to what I had before?

I was a a little too hasty. Several times after your latest, I had to go back to reenter the info I entered since the computer make me sign in to start again. (this even after I relocked the changes.) Then another problem arose. I always just put the Mac to sleep and don't completely turn it off. For the last two times I cannot get it to wake up and have to shut it off and start all over again. I now wish I never downloaded this new OSX.
Any ideas about this?

Recurring Printing Problem with HP Office Jet Pro L7590 w/Windows XP operating system

This printer is a real workhorse but frequently, when printing large documents from the internet, the type changes from regular print to total giberish -something similar to a Russian Script. It does this midsteam into the document and there is no error message or any indicatin that something is wrong. It is also hit or miss-sometime I get the entire document in English and sometimes I don't. Unfortunately, I'm wasting a ton of paper and time to redo everything when it occurs.
Other than the above, it works fine. Any suggestions on how to correct?

So the printer will begin to print garbled text in the middle of large document print jobs, from time to time? Is this correct?
How is the L7590 connected to the WinXP PC? (USB, ethernet, wireless)
How long is the USB cable if connected this way?
How far away from the router is the printer if connected wirelessly?
If usb connected, how old is the USB cable?
It is possible that this problem is coming from a connection problem. If a minor connection issue exists, then it can leave portions of the print language being sent as commands to the printer out. This can change the printer's interpretation of the printer command language.

I have a macbook pro with OSX Mavericks 10.9.5 and some keys that are not working. Specifically, the enter/return button, the "p", "0", ";", and all the function keys. What's really weird is that happens randomly. I've never spilled anything on it

I have a macbook pro with OSX Mavericks 10.9.5 and some keys randomly are not working. Specifically, the enter/return button, the "p", "0", ";", and all the function keys. What's really weird is that happens randomly. I've never spilled anything on it, and I can't for the life of me figure out how to fix this. Can anyone help? of course this happened after my warranty expired.

**update**
I don't know if this will help someone but I am posting this for that purpose. In the past when I first had this problem, I'd read a post somewhere (sorry, long ago, don't have the link) where an individual was having the same problem and they stated that when the MBP got heated, that's when the keys would stop working, and they went into the MBP and jiggle some stuff around (a specific wire, I'm not electronically inclined so I know NOT of what they spake!). Well I didn't want to do that but it always stuck in the back of my mind. I had given up, really, and was planning to take my MBP to the apple store. But by chance one night I left my MBP on the floor where it's cool, and when I turned it on, the problem went - poof! It seems there was some validity to the post that spoke about heat, because my problems started when I would stream foreign dramas on my MBP for hours at night, and I would hear the fan going off all the time, and in the mornings, my "p", "enter", "0", ";", and all the function keys would stop working.
So, maybe try keeping the MBP in a cool place when it's off. Since I've started doing this overnight every night (keeping it on the cool floor, out of reach of any big feet), I have not had a single problem with my keyboard.
Hopefully this might help someone.

Problem with Billing due list, relating to Returns Credits

Hi
I have a query/ problem with the billing due list
I cannot seem to be able to create billing documents via VF04 for Returns credits, only via VF01
I have changed Billing relevance of Item category REN to be A - Delivery related,
As we previously had problems with incorrect qty being billed IF returned delivery quantity was different to Returns order quantity - this resolved the problem but I now cannot create billing via billing due list
Messsage appears ' delivery type LR cannot be invoiced with billing type F2'
If i enter billing type RE then the document is not gettting picked up at all
when Billing relevance of item category was B, order related - all seemed to be working ok
I have copy controls set up from LR to RE with item category REN, with pricing type G
Please advise how i can get the Returns to appear in the billing due list
many thanks for your help
Tony

Hi,
In copy controll VTFL
LR to F2 at item level
REN >>> Deatila >>> Put billing quantity as - D delivery related

Sharing problem from OSX mavericks to windows 7

I want to acces a windows 7 shared folder with my mac. I have schared the windows folder and have given full permission to evereyone.
The workgroup name, login and pasword are the same on the MAC and Windows 7 PS.
I have don a ping test and the result was ok, i've tested with another windows pc and i could connect to the shared folder, just with OSX mavericks it will not work.
What could be the problem?

I think Apple disabled the Internet sharing, I have a Airport Express and was sharing my internet with my other boxen that need a Ethernet cable to download wifi drivers and one software update later it just stopped.
I think I saw that theory posted elsewhere on the internet. I would think that it would be some software bug rather than Apple giving a no-go to sharing over an adhoc.

Can't install Flash Player on Mac with OSX Mavericks

Hi I have a MacBook Pro with OSX Mavericks and I have tried to install then uninstall the Flash Player and each time a box pops up and says the application quit unexpectely. I hvae tried this several times with no luck. Any suggestions?

On my MacBook Pro I have the same problem, it says that Flash isn't installed, but Flash is working perfectly fine in Chrome?
That's because Chrome has its own proprietary Flash Player embnedded by Google. There are instructions for a thorough "clean install" here: http://forums.adobe.com/thread/1343084 if the regular clean install won't work.

Can I set up a ps3 media server with OSX Mavericks with out additional software?

I cant find any thing on the net about this. Does any one here know how I might set up my PS3 media server with OSX Mavericks with out additional software?

You might want to consider starting a new discussion. Since this one is marked solved, less people are likely to look at it. You can link to this one.
Try control - clicking on it and see if you get an open option. If not, go to System Preferences/Security & Privacy/General and set it to 'Allow apps downloaded from' anywhere. For safety, you might want to change it back to something more secure.
