Re-Installing Yosemite... checklist of what to do?
Hi, I'm getting ready to re-install Yosemite on my Mac Mini mid 2011 because of an issue where my Mac becomes unresponsive for a brief time and I I asked for help but I didn't get a response in this thread: Unresponsive Mac: Yosemite is unusable! HELP!
My only option seems to be a complete re-install of Yosemite unless someone can help me?
How often do the experienced users on here do a fresh re-install of OSX by the way?
Could someone please link me to a checklist of what I need to do before I erase my Mac's HDD and re-install Yosemite?
Thanks!!!
You can reinstall the OS X on top of what you have without losing your user files, photos, settings, bookmarks etc
A fresh install you have to erase or re-format the drive, this wipes out all data, so make sure you have a recent back-up.

Bootclone for example

I installed Yosemite and now my computer is slow when logging in. Also when I type my password, a bar appears measuring the process and then all of a sudden the screen images are distorted. After that my home screen appears and everything seems normal. What can I do to fix this?
Here is what the etrecheck results are:

16 mo young Mac Pro will not turn on. Dead. Why. No problems ever! Installed Yosemite and did not boot up after. Did that kill it? To young to die. What happened?what do I do now??????? Help!
Note that you don't have a Mac Pro as stated. Your profile says you have a MacBook Pro. Please clarify as they are entirely different computers. If nothing below works for you, then make a Genius Appointment and take it in for service.
Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
computer and after the chime press and hold down the OPTION key until the boot manager

When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.

I may have totally screwed myself but...after installing Yosemite without checking for potential problems with Adobe software, my CS4 Design Premium suite wouldn't open. So after consulting some forums, I deinstalled it, but I only have disks for my old CS3. When I got the CS4 upgrade I downloaded it, back in 2011... What can I do?? Everything was fine before I upgraded that *#$%* Yosemite.
You can find the CS4 download here: https://helpx.adobe.com/creative-suite/kb/cs4-product-downloads.html

While installing yosemite, after agreeing to the terms it ask for a disk drive to select for install. All of mine that come up say that yosemite cannot install to that one. This includes my HD. What is the problem?
I subscribe to the "if it ain't broke don't fix it" and it currently works fine with 10.9.5, or it works fine as my start up disk presently.
The reason I suspect FDE is the culprit is from reading this:
http://fairerplatform.com/2014/06/can-mac-run-os-x-10-10-yosemite/
and in the known issues for installation it mentions "may be unable to install over an encrypted volume" and while this is from an older version, I'm going to hold off now until I've seen that 'Known issue' resolved. I'm having trouble finding a copy of the current release notes.
This account of installing Yosemite seems to have hit a number of the Known Issues:
http://onword.co/6642/
My FDE linux installations know how to upgrade themselves on a full disk encrypted systems. I'm a little disappointed this is an issue at all, and am going to wait. It's not worth the risk of bricking this machine. -
What is best practice for installing Yosemite
I am currently on OS X Mavericks version 10.9.5 Macbook pro 13. 2.6 ghz intel for i5, 8gb 1600 mhz ddr3.
I am now downloading yosemite 10.10.1 but since i've been reading all these negative feedback so far, i am having second thoughts if i should continue to install the upgrade or not.
Any suggestion What is best practice for installing Yosemite? Or is it not yet time to upgrade since the platform is premature yet?
Thanks in advance.Check your apps are compatible with 10.10 - roaringapps.com
http://www.etresoft.com/etrecheck can show what is running & installed - look for updates on the developer own sites.
If you have many kernel extensions or startup items look for updates to them too
Take a full bootable backup to another disk via Carbon Copy Cloner, Super Duper! or Disk Utility
Disconnect the backup before you begin any install (ideally set it aside & leave it untouched incase you need to go back to 10.9)
Personally I prefer a clean install when there are signs of multiple migrations (if you have upgraded several OS for a period of years). Setup Assistant/ Migration Assistant can import user data from a backup, but consider that Apps & 'other data' should be manually reinstalled from the latest versions.
If you clean install (erase the HD before installation) then make sure you deauthorise iTunes & any other apps that are associated online (like find my Mac).

Clean Install Yosemite onto new SSD (Also, what is TRIM?)
Hi,
I've been researching how to replace the Hard Drive on my Late 2011 13inch Macbook Pro (MacBookPro8,1 / 2.4 GHz / Intel Core i5 / SATA III) with a new SSD (maybe a Samsung 840 EVO) and clean install Yosemite onto it. I've found a few ways to do this on the support forums and the macrumors forum, but I want to confirm if I can do it this way:
1. Plug new SSD into the Macbook via a USB cable
2. Download Yosemite onto current Macbook Hard Drive. When I'm prompted to install, chose the new SSD from the list. Complete Installation.
3. Remove old Hard Drive from Macbook and plug new SSD in it's place (and not in the optical bay).
Would this work? I have another external hard drive with all of my documents, pictures and music on which I'm just going to manually remove over, and have no problem doing. I can also download the iLife programs directly from the App Store so I wouldn't be missing out on those either (I do have the iLife '09 discs too). I've also read about creating a bootable USB using DiskMaker X, but I feel the route I outlined would be easier.
Am I missing anything? I do have the EFI Firmware v2.7, so the problems the 2011 MacBooks were having with SATA shouldn't be an issue during this. Also, during my research, I found a references to something called TRIM. Can someone explain TRIM to me?
Thanks,
SteveThanks for the response and confirming I can clean install Yosemite onto a new SSD using the process I listed in my initial post.
I have a 13'' MacBook Pro with Yosemite already installed onto it so my graphics card should be set. After almost a month of using it, I haven't noticed any issues on that end.
I guess this TRIM thing is a totally separate subject from this thread. I read Apple is no longer supporting third-party SSD for TRIM support. If you turn it on, but keep a security feature on, you risk your computer not booting correctly. It looks like the only way to have TRIM enabled on a SSD using Yosemite is to have an Apple supplied SSD, or an SSD that can trick Yosemite into thinking it's Apple supplied (like the Angelbird Wrk for Mac SSD).
I've also done a good amount of research that TRIM is only necessary if you're saving a lot of items to the hard drive in one sitting (like photoshop). I primarily use my Mac for Pages (which saves my documents into the cloud now), iTunes and Safari. I guess this would fit me into the "casual user' criteria? I've also read that if you don't use TRIM, your SSD uses "Garbage Collection" (which actually sounds terrible) to keep the SSD informed on what data can be overwritten since it's been deleted by the user. I read that most modern SSD hard drives have a pretty decent Garbage Collection function, so if you leave your computer idle, keep "Put the hard disk(s) to sleep when possible" unchecked, the SSD will run Garbage Collection on it's own and that should be sufficient enough to keep the SSD in good working order. -
I'm thinking of upgrading from v10.6.8 Snow Leopard to OS X Yosemite. I know, I'm years behind, but it has become a necessity. My Mac is becoming slow and is incompatible with many softwares and websites. Does anyone know of any problems associated with this upgrade? What are the implications and/or consequences of installing Yosemite? Does it effect functionality of v10.6.8 software or hardware? Are there any precautions I should take before the installation? I have read some posts about Macs slowing right down after installing Yosemite. Any insights and information (in layman's terms please!) would be very useful. Thanks.
Huge thanks for your response Michel. I apologise for the delay in getting back to you. I have done as you suggested, the details are pasted below. Clearly there are some applications I need to remove and no doubt my HD could do with a 'spring clean'. My Mac 'Safe Booted' when I turned it on this morning.
I use many different softwares, some web-based. The decision to upgrade to OSX Yosemite is because I was unable to attend a Webinar this week using GoToMeeting downloadable software. GoToMeeting have upgraded their system and my OS is no longer supported. Other websites like VImeo no longer support my version of Safari. I tend to use Chrome if Safari isn't compatible.
Problem description:
I'm thinking of upgrading from v10.6.8 Snow Leopard to OS X Yosemite. However I have noticed that my MacBook Pro becoming ‘slow’ over the last 3 weeks and therefore might have some issues that need to be resolved before I even consider installing OSX Yosemite. Over the last week my Mac has Safe Booted on three occasions, so clearly there’s a ‘glitch’ occurring.

i just installed yosemite on my mcb pro mid 2012 with a clean install. so i only had the new os x yosemite running on my mac. everything went perfect. than i installed win8.1 with the bootcamp assistant and also everything went perfect.
But here's the Problem:
When i'm using Windows 8.1 and i go to the "Computer" window where i can find my hdd partition "Bootcamp (c;) there is only this Partition. the mac Partition is missing.
so i am not able to read the files on my mac Partition.
Before i installed yosemite and win8.1, i was running mavericks and win7 on my macbook pro and i haven't had this Problem. i was able to see and read my mac Partition also on Windows 8.1???
is there any solution for this Problem???

New iMac with factory installed Yosemite underperforms compared to much older Macs. What do do?
Very, very disappointed with Yosemite. Brand new iMac 27 lags awfully compared to my MB 17 and even MB Air. Discounting the fact that many apps will not even instal, those that do (and which never crashed before), fall apart on iMac at least once a day (Garage Band, Firefox, SoundForge, SpeakIt!). The most madenning thing is the networking – both Mavericks machines take seconds to copy 50-100Mb files to Time Capsule via wifi, while iMac needs minutes. Even reading folders on network drives takes forever. And sadly, network file swapping is a must, since AirDrop in 10.10.2 is totally useless (persistently fails half way). The only option seems to downgrade to 10.9... Any ideas are appreciated.

Recently, I installed Yosemite on my MacBook Air. After that I had no sound. Not even the start up chime. In Sound preferences there are no input devices and no output devices. I have had three meetings with Apple support with no results. Can anyone help? This seems to be a regular problem.
Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
computer and after the chime press and hold down the OPTION key until the boot manager
screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.
5. Reinstall Yosemite from Scratch:
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
