Macbook Pro 13-Inch 2015 takes long to boot up

I brought the mid tier 256gb Macbook Pro 2015 13 Inch in April. I brought it with the RAM upgraded to 16gb. Not soon after I brought it I updated the software to the latest version of Yosemite. (which in hindsight I probably shouldn't have done).

Since then it has taken ages to boot up, and recently the fan is constantly on although I am just browsing the internet with no other applications running in the background.


Any help would be great, thanks.

MacBook Pro (Retina, 13-inch,Early 2015), OS X Yosemite (10.10.5)

You have a corrupted update.


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 the 10.10.5 update: OS X Yosemite 10.10.5 Combo Update.


5. Reinstall OS X: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.


Reinstall the 10.10.5 update: OS X Yosemite 10.10.5 Combo Update, if required.


Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
