Clean reinstall for yosemite 10.10.3

i downloaded new update 10.10.3 on my early 2011, 2.2 GHz, plenty of space. I get the WHEEL OF DEATH ON ALMOST EVERY APPLICATION. Would a clean reinstall help and how do i do it?

these are the instructions on how to do a fresh install of Yosemite:
Backup your data to an external drive before doing a clean install.
1) Restart computer while holding down the Option key. A screen should show up allowing you to select either Macintosh or Recovery
2) Select Recovery. Choose Disk utility.
3) Select the name of the drive/partition you want to erase on the left. If you have a Boot Camp partition or any other partition you'd like to preserve, select "Macintosh...", otherwise, select the name of the drive. (this doesn't delete the recovery partition)
4) choose the "Erase" tab. Verify that Format is set to "Macintosh OS Extended (Journaled)" and choose a name for the drive such as "Macintosh". click the "Erase..." button
5) after the erase is complete press command+Q to return to the previous screen. Choose "Install Yosemite" and follow the instructions (this will be a fresh install)
6) after the install is complete and you wish to restore your data, i do not recommend having Yosemite automatically restore your home folder as something in the Library of your home folder may be causing the spinning wheel.

Can't connect to time capsule after clean reinstall of Yosemite

Hi
I was having performance issues with my MBP and it looked like a clean reinstall of Yosemite was the answer. I have performed the reinstall and re install my apps. I want to bring back my data from my time capsule but I can't connect.
When I tried in Migration Assistant it said there were problems connecting. If I use Finder, it is visible under the Shared heading but it says I can't connect.
How can I reconnect my time capsule so that I can bring back my data?
Thanks in advance.

Reset the TC to factory.. redo the setup from Yosemite version Airport Utility.. no files are lost doing this.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
When you do the setup, give the TC short names with no spaces and pure alphanumeric characters.. same for passwords.. 8-20 characters.
Now in Finder mount the TC by IP address rather than by name.
Use Go, Connect to Server from top menu,
SMB://10.0.1.1 for example.
It has to be static IP which is default in router mode but not so in bridge.
If you are bridged use the name or fix the IP.. dhcp reservation in the main router.
Type in like this for name.
SMB://TCname.local (replace with your new name and local is default domain .. it is important and helps).
Remember to save the password in the keychain when asked.
Good luck.. and if it fails clean install Mavericks or even Mountain Lion.. they work so much better.

How to format & clean reinstall OSX Yosemite?

My MacBook Pro has the iWorm. Deleted the folders suspected of iWorm (JavaW) and restored host file. Thinking of formatting and clean install of Yosemite back.
I suspect I got the iWorm from pirated Adobe software, and others.
I've checked my backup in Time Machine and I suspect all of it has the same thing going on with the iWorm.
Nothing much that is important in my computer other than music, some school projects and photos. Can I just copy what I deem important and then reformat and reinstall Yosemite? And if I do all that, do I have to re-register back my data about the MacBook, like registering my MacBook's serial key etc?
Thanks

Is there another way besides using a thumb drive? Not having one currently.
Can I just erase the hard drive via Disk Utility or reset back to factory settings, and then download Yosemite through App Store and install again?

Hello. I tried to clean reinstall of Yosemite, but something went wrong and i got a flashing folder with a question mark. when i press cmd+r i get the globe spinning, but after seconds i got an error ( 2006F )

Hi kamide,
I understand that you are seeing a flashing folder when attempting to restart your computer after an attempted OS update. Here is an article for you that deals with this issue and can help you address it further:

Clean Reinstall without App Store download?

I need to do a clean reinstall. (I have a problem with Final Cut Pro X that is resolved when I create a new user and work from there).
I don't have a Recovery HD on my system (I thought it was automatically created when you install the OS). To further complicate matters, every time I try to download Mountain Lion from the App Store, it hangs at 425 MB (downloaded).
I've repaired permissions, deleted cache files, checked the App Store for unfinished downloads etc etc but every time the download starts, it gets to 425 MB and then locks up with the message:
"OS X Lion failed to download - Use the Purchases page to try again."
(This is not a helpful message - especially when you've "tried again" a dozen times.
I've also deleted any file or part-file that's been created in the Apps folder.
I'm totally at a loss to know how I can create a Recovery HD if Mountain Lion won't download from the App Store.
I tried downloading Mountain Lion onto my partner Gill's iMac (she's was a little apprehensive about it). I was hoping to create a Recovery HD on a 16GB CF card.
If THAT worked I would probably have been in business because I could have used it on my Mac Pro.
The download onto Gill's iMac failed at 124 MB (Downloaded).
I suspected our broadband connection, but I just watched one of our videos on it, and it played perfectly - in fact the buffer indicator showed that the 4 min 44 sec video was fully downloaded by the time it had been playing for 35 seconds.
I guess the fault must be with the App Store - although I downloaded FCP X from there last night.
Assuming I eventually resolve this, it's a clean reinstall for me - and my first job after installing the system on any new Mac in the future will be to make certain I have a Recovery HD.
I hope someone can shed some light on this.
Andy

Thanks for your help, Barney,
I agree. If you vacuum your living room carpet, you don't empty the contents of the container back onto the floor so I don't refer to "clean install" if I intend to drag all the garbage back onto my system drive. If I do a "clean install" that's what it is - a very long tiresome process.
I'm beginning to think the new user option is my only one. I've tried repeatedly (including using your suggestions above) and failed every time to get Mountain Lion to download.
I doubt it would consistently fail at 425 MB if the wifi were causing the problem, but all the same, I connected via ethernet cable - to no avail. I even tried pausing the download at 400 MB, then switching off and disconnecting the router for five minutes - but that had no effect either.
And I tried downloading at 5 am this morning, just in case it was heavy local usage that affected it, but again, it wouldn't be consistent.
I just paused it again, and will restart the Mac before resuming, but I don't hold out much hope.
If anyone has any ideas on this, I'd be most grateful.
Andy

Preparing for clean reinstall

I want to backup data and download OS to have a fresh system.
I'm aware that I need to back up docs, etc, but wondering if there are system things I must attend to. (Or to which I must attend if you are one of thos snoonty Englsh majors) Ha.
Thanks for your kind attention.

Very kind of you to offer.
I've been running Disk Utility, Permissions and repair, and find strange stuff. Incorrect printing info for instance when I have not changed or used other printers in years. And, all kinds of problems with languge permissions and I never use anyting but US English. (I deleted all the other languge options). Things would get VERY slow, at all programs, and only by running Disk Utilty could I correct it....and then only brielfly sometimes. Some programs would not stop an I had to force close them. I deleted all the APPS I downloaded but never used and then deleted all instances of the files from the library. (as far as I know) That seemed to help. I had been using Firefox and switched to Safari (don't know if that helped or not)
Whatever....I'm now back to about normal speed and not many strange things going on. Yet.
That's a brief overview. It just seems that a "clean reinstall" would be a good solution. But, I see your "background" here and note you are a long time user who seems to have stellar reputation and I'd gladly (and thankfuly) be happy to hear whatever you have to offer rather than the clean reinstall I'm considering.
Thanks so much for your kind attention,

How to backup with Time Machine for complete clean reinstall of OS

My iMac has been getting slower and slower as the months go by and with each new software update. It used to be a lot faster than this when it was new.
I'm thinking the best solution might be to do a complete clean reinstall of the OS. My question is, if I have Time Machine backing up of all the users Documents, Email, Address, Book, iTunes Library, and iPhoto Library files, can I just go ahead and blow away everything on the machine? That is, after reinstallation, can I just plug in the hard drive, turn on Time Machine and get all those data files back in the right place without difficulty?
Or am I better off meticulously and manually moving the appropriate files/directories to an external harddrive and then fitting them all back into place manually afterwards?
(NOTE: I used to have to do a clean re-installation of XP every year or so to keep the system nice and snappy -- it would invariably get slower and slower over time. Since I got my iMac (Tiger) I had never had this creeping slowness problem, why is it happening now with Leopard?)

slegge,
This might give you some ideas.
Using Time Machine to Restore You Entire System
Q: Can I restore my Mac from a Time Machine backup?
A: Yes, you have several options: (In all cases Mac OS 10.5 Leopard is required as previous OS X versions will not work with Time Machine backups.)
*Full Restore Via Migration Assistant & Time Machine*
You can use the installation DVDs that came with your Mac and reinstall Leopard (Mac OS 10.5). During the installation process you will be asked if you would like to Migrate data over from your Time Machine backups. The advantage here is that you start with fresh system software. The disadvantage is that you may lose many of the personal preferences/settings that had been established with the previous system. But this may be only a minor inconvenience to reestablish these. Depending on whether you choose to migrate your applications over as well, you may be required to reinstall any 3rd-party software or standalone Apple programs. Don’t forget to run Software Update once the initial installation is complete to bring your system up to date. Using Disk Utility at this point to repair any permissions issues is advised as well.
*Full Restore Via Time Machine Only*
Alternatively, you can use the installation DVDs to do a full system restore. Insert the installation DVD. When the welcome window appears, go to the Utilities menu and select “Restore System From Backup…” and choose the drive that your Time Machine backups are on. Then select the date of the backup you would like to restore from. This will completely erase your internal drive and restore your system to a relatively same condition it was in on the date of the backup you choose. (See this article for a list of files that TM does not restore, http://shiftedbits.org/2007/10/31/time-machine-exclusions/) The advantage here is that you retain many of the personal preferences/settings that had been established with the previous system. Additionally, no further installation of 3rd-party software is required. The disadvantage is that BECAUSE you retain many of the personal preferences, settings, and system files that had been present with the previous system, you run the risk of reintroducing problems you experienced with the previous installation, including any issues that necessitated the OS reinstall in the first place. Using Disk Utility at this point to repair any permissions issues is advised as well.
*Full Backup After Restore*
Bear in mind that in all cases Time Machine will perform a full backup after a full restore. This is normal. Time Machine will resume incremental backups after the full backup has completed. To view previous backups, Control-click or right-click the Time Machine icon in your Dock or Option-click the Time Machine menu extra and Choose "Browse Other Time Machine Disks," then select your previous backup volume. You will enter Time Machine and be able to browse your previous back ups and restore files. (http://support.apple.com/kb/TS1338)
Hope this helps.
Cheers!

HT2474 I did a clean reinstall of mountain lion and for some reason the dock keeps osx lion format

I did a clean reinstall of mountain lion and for some reason the dock keeps osx lion format. Does someone how to uptade only dock application?
Tks

Try doing a Dock restart using the following Terminal command:
killall Dock
Log out/in and test. If that doesn't work.
You need to look in your user Library/Applications Support/Dock for the .db. Hold down the option key while using the Finder “Go To Folder” command. Enter ~/ Library/Applications Support/Dock. Move the .db to your desktop.
If you prefer to make your user library permanently visible, use the Terminal command found below.
http://osxdaily.com/2011/07/04/show-library-directory-in-mac-os-x-lion/
You might want to bookmark the command. I had to use it again after I installed 10.8.4. I have also been informed that if you drag the user library to Finder it will remain visible.
Then try a dock reset.
Applications/Utilities/Terminal enter the command
killall Dock
Log out/in test. If it works okay, delete the .db from the desktop.
If the Dock is the same, return the .db to where you got them from, overwriting the newer ones.

Running Windows 7. After Firefox updated to Version 33 Firefox wouldn't start. Received "Couldn't load XPCOM" message. Followed directions from Firefox forum to do a clean reinstall. Downloaded file from Mozilla.org using Internet Explorer since Firefox isn't working. Removed old program file. When I try to run the Firefox Setup Stub 33.0 file it keeps stopping. The message says "Your download was interrupted". I've tried running it several times all with the same result. I've also made sure that I cleared previous downloads before re-trying. Does anyone know how to resolve this problem? Thanks for your help.

Recovery manager won't start for clean reinstall of Windows 7

I have an HP Pavilion Elite HPE-110f that is 4 years old. Everything was fine until a couple of weeks ago started getting RAID messages on startup and other little qwerky things. Then last week the dreaded BSOD showed up. I shut down the computer and tried to restart, but got error messages that the computer couldn't start. I then tried everything I could think of - startup repair, tried to boot in safe mode, recovery from partitioned drive, system restore - nothing worked. I have the recovery media from HP but was saving that as my final option. I tried to do a clean reinstall today from the discs, but now the recovery manager won't even come up. Can somebody PLEASE help me get my OS back?

No, it wasn't an error message. It was just notifications about different things being accessed on port1. I just assumed it was startup items loading, but I had never gotten notifications about them before. I just tried again to reinstall from recovery discs. Pressed esc and got the boot menu, selected the dvd drive and you can hear it running, then it slows down to nothing and I get no recovery manager opening. I turned off the computer again and pressed f9 when I turned it on. Diagnostic show processor and memory are fine, but I get an error code of "BIOHD-8" on the hard drive. Any suggestions?

After a clean install of Yosemite in iCloud remained links, which were opened in Safari on the Mavericks

Hi leonie,
It looks like once my computer was subject to a clean install of OSX Mavericks, programs installed with iLife, i.e. iWeb, GarageBand. iPhoto, etc, were removed from my HD and cannot now be reinstalled.. I form the impression that they are not on the installation DVD's that shipped with my computer, and having examined the disks by placing them in my machine, there is no way I can tell whether that is correct, since there is no 'button' that allows me to look for their presence on the disks.
If you can shed any light on that conclusion, I'd be grateful for any advice you could offer. I guess it's not super imperitive that I have GarageBand '09, I can get by without it, but it would have been nice to have, and a couple of my songs use loops that were from GB '09, and these are now absent from the songs when played back in GB X. Of course, I cannot download the '09 version from the App store. Looks like Apple has me borked!
Thanks for your help, anyway, I'm always pleased to see your name here..
Regards, Ontradio..

MacBook Air 2010 Very Slow (even after clean reinstall)

Hi,
Problem
The performance of my Macbook Air 2010 has slowed to the point where I can hardly complete basic tasks. For comparison, I use a MacBook Air 2013 at work and do not experience the same performance issues, so I believe my expectations are not unreasonably high.
My Question
Can you please advise on what I can do to troubleshoot? I've tried the solutions listed below, all of which have failed.
I'm grateful for any help you can offer.
Problem Description
Switching contexts or tabs, operating within applications (such as Chrome, small Excel spreadsheets, navigating files), and browsing the Internet has become a slow, laggy and crash-filled experience.
When right-clicking an icon and selecting 'Open With', Finder frequently times out or requires time to populate a list of applications.
Machine is slow to the point where, unless a solution presents itself, I'll have to get a new MacBook Air.
What I've Tried
'Religiously' close all applications after use; extremely conscientious of number of applications running and their resource requirements.
Clean reinstall of OS X.
Storing all media on external hard drive to create more storage space.
Clearing cache for all browsers regularly
Always running machine on battery power
Regular reboots
Machine Specs:
MacBook Air 13-inch, Late 2010
OS X Yosemite Version 10.10.2
Processor: 2.13 GHz Intel Core 2 Duo
Memory: 4GB 1067 MHz DDR3
Graphics: NVIDIA GeForce 320M 256 MB
Storage: 87GB free of 250GB

Thanks, dominic23.
Unfortunately, it did not work.
-Tried starting in safe mode, resetting SMC, and repairing disk. Resetting the SMC helped upon reboot, but performance degraded swiftly and back at a low within 30-minutes.

Blue Screen after clean reinstall snow leopard

I have a mid 2011 that came with Snow Leopard and disks. I upgraded from there to Lion - then whatever came next and to Mavericks and finally Yosemite, which was a nightmare for me. I did not use disks of any of the rest. So I just decided to take my disks and go back to Snow Leopard. I did this and it asked to go to disk utility and repair both the HD and Permissions. It came out ok, but there was an instance where looking at the list in HD repair, I saw Suid File System Library Core was moved and cannot be repaired. I went ahead and erased the Hard Drive. Then closed out and installed Snow Leopard. I'm not sure I did it right because I had to rename the new start up disk and typed in unnamed 1.
after that I was able to start up to Snow Leopard. It worked fine until I tried to download all the updates. Then it didn't seem to restart, but just went to the sign in screen. So I had to keep shutting down and turning it back on. No updates. One of times I started up, I got the blue screen after the apple and gray screen.
Also on start up the apple comes up without the chime. Last night I got some instructions from a similar situation and tried to use my disk to a clean reinstall all over. It didn't work, still the blue screen. (it does fine in safemode.)
I need help to get this mac running. If someone can help me......

Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. After you finish Setup Assistant will complete the installation after which
         you will be running a fresh install of OS X. You can now begin the update process
         by opening Software Update and installing all recommended updates to bring your
         installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

Question about bootable USB installer for Yosemite

After having wi-fi issues last month, I reinstalled Yosemite (clean install). I only mention that so that it is understood that I have a pretty good understanding of how this process works.
But I am old school and I like physical media for various reasons......not least of which would be in the event I ever have future problems getting online to obtain the download from the app store. So this evening, I decided to create a USB bootable installer for Yosemite. I used the following web site, which is quite thorough in explaining the process:
http://osxdaily.com/2014/10/16/make-os-x-yosemite-boot-install-drive/
I followed the instructions and successfully created my bootable media using a USB drive. But because I wanted to put this newly created bootable media to the test (without actually reinstalling anything), I just restarted the computer (command R) to ensure I could boot to the USB installer. I then clicked on disk utilities and noticed the following folders (and subfolders):
Macintosh HD
---Macintosh HD
31.95 GB PNY USB
--Install OS X Yosemite
disk 3
--OS X Install ESD
disk 4
--OS X Base System
Now for my question, does anyone know why I have these multiple folders on the USB drive? I can understand the first set (Macintosh HD and its subfolder) being my current OS X setup. And the second setup of folders (31.95 GB PNY USB --Install OS X Yosemite) being the actual USB installer. But what's up with those last two sets of folders called disk 3--OS X install ESD and disk 4--OX X Base System? Does anyone know? Perhaps one of those folder sets under disk 3 or disk 4 would be a hidden partition? But why both disk 3 and disk 4 folders?
I just want to make sure everything is correct here; and that I am good to go with the USB bootable media! I carefully followed the instructions using the above link to create this USB drive.

FYI
my process just completed: here is what I see when it is done... (the first you saw in my earlier post. It took about 15-20 minutes.
To continue we need to erase the disk at /Volumes/Recovery.
If you wish to continue type (Y) then press return: y
