Jun 12, 2015 9:54 AM in response to robpeleby Eric Root,Please post the full Etrecheck report.
Do you have an administrator password set? Security & Privacy won't accept a blank password.

Jun 12, 2015 10:44 AM in response to robpeleby Linc Davis,You should have erased the internal drive, installed OS X, and then restored only your user files from a backup. Is that what you did?

Jun 12, 2015 2:09 PM in response to Eric Rootby robpele,Here is the full report. Yes the user has a password. In answer to Link Davis' question. The previous owner wiped all data and apps from the machine. Don't know if he erased the drive, but is was pristine and ready for setup- which I did, and then downloaded the user folder from my daughter's old macbook, using crashplan where it had been backed up. In the process I had to change the name of the user folder to match her old one. To do that I had to create a new admin user and log in to that account.
So I did pretty close to what Link asked if I did.

Jun 12, 2015 2:39 PM in response to robpeleby Linc Davis,The previous owner wiped all data and apps from the machine.
You—not the previous owner—had to do that. Your copy of Yosemite is unlicensed, since he had no right to transfer it to you, and the machine is in an unknown, untrustworthy state.

Ok, but the fact is I didn't do it. So how do I solve the problem that I have?

Jun 12, 2015 4:56 PM in response to robpeleby Linc Davis,Before acquiring a second-hand computer, you should have run Apple Diagnostics or the Apple Hardware Test, whichever is applicable.
The first thing to do after acquiring the computer is to erase the internal drive and install a clean copy of OS X. You—not the original owner—must do that. Changes made by Apple over the years have made this seemingly straightforward task very complex.
How you go about it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
It's unsafe, and may be unlawful, to use a computer with software installed by a previous owner.
1. If you don't own another Mac
a. If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller—not from eBay or anything of the kind. If the machine is very old and has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
b. If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for a MacBook Air. You should have received the media from the original owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To start up from an optical disc or a flash drive, insert it, then restart the computer and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
c. If the machine shipped with OS X 10.7 or later, you don't need media. It should start up in Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
d. Some 2010-2011 models shipped with OS X 10.6 and received a firmware update after 10.7 was released, enabling them to use Internet Recovery. If you have one of those models, you can't reinstall 10.6 even from the original media, and Internet Recovery will not work either without the original owner's Apple ID. In that case, contact Apple Support, or take the machine to an Apple Store or another authorized service provider to have the OS installed.
2. If you do own another Mac
If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to prepare a USB device, then start up the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can start from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
3. Partition and install OS X
a. If you see a lock screen when trying to start up from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another service provider to be unlocked. You may be asked for proof of ownership.
b. Launch Disk Utility and select the icon of the internal drive—not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
c. An unusual problem may arise if all the following conditions apply:
OS X 10.7 or later was installed by the previous owner
The startup volume was encrypted with FileVault
You're booted in Recovery mode (that is, not from a 10.6 installation disc)
In that case, you won't be able to unlock the volume or partition the drive without the FileVault password. Ask for guidance or see this discussion.
d. After partitioning, quit Disk Utility and run the OS X Installer. If you're installing a version of OS X acquired from the App Store, you will need the Apple ID and password that you used. When the installation is done, the system will automatically restart into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
e. Run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the original owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed—you have to repurchase them.
4. Other issues
a. If the original owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're irrevocably linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
b. If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.
c. When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a lifetime limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an iCloud account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information. The setup limit doesn't apply to Apple ID accounts used for other services, such as the iTunes and Mac App Stores, or iMessage. You can create as many of those accounts as you like.

But what I would rather do is simply fix the items that have problems that I listed in my initial post. I do own 5 other currently used Macs ( and 3 pre intel macs in the closet), though none of them have Yosemite installed, as this wone does. I would rather not reinstall the free os 10.10 but simply register me as the new licensee of this version.
Apple has clearly made it complicated (for a retiree like me), but maybe there is a simpler way. What you young folks call a hack?

Jun 12, 2015 5:16 PM in response to robpeleby dianeoforegon,I've seen these fail when there is not enough memory available. You only have 4GB RAM. You need to be careful not to open too many apps at once. It's especially important not to open too many tabs or windows in your browser.

That's not possible. I have no other suggestions. Good luck.

Jun 12, 2015 5:26 PM in response to robpeleby dianeoforegon,If it is memory related there is nothing you can do to add memory. The Air does not allow you to upgrade RAM. Your only alternative would be to not run so many apps and be very careful when browsing.
El Capitan is supposed to be much better at launching apps and managing memory. Perhaps when it's released you will see improvement.

Jun 12, 2015 5:28 PM in response to Linc Davisby robpele,Thank you again Link,
I appreciate your concern, your time and your help.
I have one more question for you. If I wipe the ssd and reinstall 10.10.3 under my apple id, can I then download the contents of the current user folder (from either crashplan or super duper) without fear that this problem will be repeated?

I don't think memory is the issue. My daughter's previous air (2012) also had 4 gig of ram. while she does open multiple browser tabs, she does not run a lot of memory intensive apps, except spotify perhaps. No games, no facetime, etc. But to be sure I will install Memory Clean on this machine. (after I fix this problem)

I don't know. That would involve analyzing the problem. What you would not have to fear is never being able to update anything again in the App Store because your copy of OS X was unlicensed, or the possibility that the operating system might be contaminated with something unknown and unknowable.
