Startup MacBook Pro-comment problems prevent health going to disk/check once again

My 13 inch Macbook Pro running OSX 10.9.5 (said mid-2012, but it was purchased in fall 2014) has had problems starting

A few weeks ago the computer is stuck on the loading screen (white, with the Apple and the buffering of spinning icon) without marketing properly. After you have manually turned off and left for a long time he worked well on the next test, so I took care of it has been saved and so didn't think much, and it works pretty well in recent weeks, sometimes being a little slow but that very occasionally and not debilitatingly so and it probably is not related to this problem.

This morning it was still once stuck on the loading screen, and try again in 5 or 6 times solves nothing. The VRAM reset did not help either. After an attempt to boot into safe mode (filled a little progress bar then disappeared and the computer continued to buffer without purpose), I once again reset the NVRAM and tried a different boot safe mode, with the same results. But this time I left it half an hour or so and on the next attempt (start normally) it miraculously worked a new and everything seems functional. After a new backup with a preparation period slightly extended backup (at least half an hour on the first abandoned attempt, then at least 15 minutes, until correct on the second trial has started), although it is common on my computer, I have enough fear turn the computer off and tempt fate again, if I want to see what can be done now.

What should I do to check the health of the disk, potentially fix it, find out why this is happening and avoid this problem again in the future?

I decided to watch from the disk utility and am confused by the Setup program. There is an 'APPLE HDD Media HTS541010A9E662' entry in the list, with a "MacIntoshHD" paragraph below, and both have different information displayed... I ran check disk on the higher level entry and it seems to be out very well ("the Volume Recovery HD seems to be OK"), but I haven't run one on the low level input as it says my computer may be "slow and unresponsive" while doing so, and I'm not entirely sure of what use there.

It cannot be storage associated with as I stil have 610 gb of free 1 terra (although a large part of what I have (130 GB) is in the other category for a reason any).

Note that all computers become slower over time even in the normal conditions of use. Generally, the experienced users erasing the hard drive and do a clean install from scratch at least once a year or every time that the installation of a major upgrade of the OS. Well sure doing so also means that you need to maintain regular and several backups.

Add more RAM or reduce the number of simultaneously executed from applications and utilities. Remove unnecessary software such as anti-malware and that promises to clean your Mac. Look for the runaway process: Runaway applications can shorten the battery life, affect performance and increase the heat and fan acti... See also:

  • MacBook Pro display problem

    Hello members of the community.

    As of recently, I have noticed some glitches when feeding on my MacBook or awakened from his sleep.

    The colors are distorted, usually with pink, green, or yellow blobs. Blobs cannot entirely replace the colors, they appear to be contained in a element would normally be. For example. the menu bar will be partially pink and white, but pink does not leave the menu bar in this area, and the Office has green lines on it.

    I tried to take a screenshot, but the problem resolves in about 20 seconds, but it's a recurring problem.

    It happens when I wake up, connection or not. I had also certain powers serious and problems of performance, such that my MagSafe LED would not illuminate when plugged on rare occasions, fan could turn unnecessarily, graphics performance were SUPER slow, and the health of my battery was running out quickly. I actually ran a report on the system at 2 different times and my quality of full load is depleting of 1.2% per charge cycle, which is very worrying. I went from 6281 mAh mAh 6138 maximum capacity after two cycles of load. I'm tracking closely it because at this rate, my battery will survive only at load cycles about 150 instead of the 1000 expected, gives me the idea that this could very well be a bad battery. The computer is also warm to the touch while you sleep, not connected to the power supply. I NAP active but even taking into account should not be hotter my iPhone did the same thing.

    I have reset the SMC, and it solved a couple of problems. The charger works fine now and my performance improved considerably (which made me feel better, either it is a high-performance laptop, a 11-inch MacBook Air should not he surpass), and battery life has improved. I feel even if it uses a lot of power in his sleep. Maybe I need to turn off the NAP and see if that makes a difference. The graphic bug still persists however, and I don't have enough time to see if the max battery is depleting again.

    In regards to the bug, is there something that can be done? Basically, I want to assure you that I took all appropriate measures or if someone else has this problem to see if it can be software related instead of my computer.

    I have the entry level MacBook Pro with the retina, last generation.

    Any constructive contribution welcome!

    See you soon.

    All by using the computer to randomly screen goes completely black.  After a few attempts at tapping trackpad or a bite or two, screen turns on but then log on to the computer.

    Hi James,

    Thank you for using communities Support from Apple! I'm sorry to hear that you are having these problems with your MacBook Pro. I'm a bit ambiguous on the screen exactly who you see when you log in, but according to your description it looks that your computer may be involuntarily go to sleep. If this is the case, you can find the troubleshooting steps in the following article useful:

    If your Mac does not sleep or wake up when expected - Apple supports

    As mentioned in this article, another possibility on laptops like the MacBook Pro is that the screen closed sensor may be triggered unintentionally. There is a small magnetic sensor in portable computers and sometimes, being close to things like briefcases magnetic closure or magnetic jewelry can cause him to think that the display was closed, which then puts the machine in a locked sleep state. If possible, you can test the issue on an office open without any potential source of interference.

  • Network with the MacBook Pro 15 "problems

    My new MacBook Pro (15-inch, mid-2015 retina) has 16 GB memory MHz DDR3.

    2.8 GHz Intel Core I & and an AMD Radeon R9 M370x PCie, in addition to an integrated

    Chipset Intel Iros Pro model. I am running OS X El Carolina Version 10.11.6, with 12 Parallels and Windows 7 for a few

    the company's programs, but I mainly work on the Mac side.

    An intermittent connection problem became constant after a week of using the computer.  My router DLink DSL (model 2750B) is two feet away from the computer.  In the system preferences / iCloud, I get "There was an error connecting to server Apple ID" my MacPro, iPad Samsung Galaxy S7 and Air 2 all connect with the same router wireless without any problem. (All my OTHER computers connected also with the same Apple ID and password without problem.  IMac 2012, MacPro, 2012 MacBook Pro, iPad 2 and the new iPad 2 Air)) I have a screenshot of the error message "None of your preferred networks are available" and in the same time to a list of all available networks, including my own.  Several times, I click on my network and get the response "the xxxxxxnetwork could not be contacted."

    I solved problem with Verizon, my provider, yesterday, and the routine test found that I have an intense tone, but the computer could not complete the test routine.  I ran "Diagnoses" several times this evening - this is after 23:00, and the report suggests that I will review wi - if recommended (fact), that I have a crowded WiFi channel (almost anyone else is in the building at this late hour) and I have to reboot the router (I did several times) and that maybe I should join a Wi - Fi network network that is associated with the Internet (like mine that works for all other devices.)

    Any suggestions on how to solve problems, or I would return the computer.  It's beautiful, and I spent a lot of time updating, installation, customization, before this stop of a Wi - Fi.  I had to buy a new router, but tests with Verizon made me doubt that a new router would solve this problem.

    Thanks for all the wisdom and strategies.  Maggie2012

    Hello

    Just to let you know, OS X only requires about 9 GB of free storage space. That does not take into account photos, music, documents, notes, etc.

    Help here > http://pondini.org/OSX/DiskSpace.html

    Restart your Mac after the deletion of data to see a difference in storage space.

    MacBook Pro 15 inch end 2011, 2.2 GHz Intel Core i7, 4 GB 1333 MHz DDR3, AMD Radeon HD 6750 M 512 MB.

    El Capitan 10.11.3 OSX

    So a week ago, I got my board logik replaced under the scheme where Apple do for free and when I got back that I updated the OS to El Capitan, and since then, my macbook was restart itself after the screen messes up, as there lines horizontally will go across the screen, the screen turns blue with vertical lines or he'll usually scrambled and the right part of the screen is on the left and the left side is on the right. This happens usually when I watch shows online, I bought a new external hard drive yesterday to replace my old and I did a full backup time machine, which took about 6 hours, I left alone and did not touch my MacBook all the time so he was backing only, and so it didn't plant once then when I look at something online it could crash a couple of times in an hour. It happens on safari and chrome.
    Guidance on how I can resolve this issue? I plan to do a clean install of El Capitan, I know that it is usually a last resort, I already have the stick bootable installation, I was wondering if anyone had any idea what to do?
    Thank you very much

    Bring the MBP and checked it.  It is indicative of hardware problems, not software.

    Hi everyone, so I bought a used Macbook 2012 pro and this is my second day with her. I picked it up upward with one hand the other day (I know you shouldn't) I tried to grab the book I had sitting under. Anyway, when I did, I got vertical lines running through the screen! I ask it immediately and simply applied a bit of pressure again left (I held from same side) and it happens again. The right did not have that. In addition, the computer went ahead and rebooted on its own a few seconds later. I'm new to Mac and I was wondering if it's just because I put pressure or if the previous owners damaged in anyway. I have 14 days to return if I have a problem.

    Thank you in advance!

  • After El Capitan on new Macbook Pro Mail problems

    Mail doesn't work properly anymore now that I use a new mid-2015 MB Pro with El Capitan.  Non-Pourriel, including remittances from my own account to myself, is marked junk and put in the Junk folder. Mail that is not marked as spam is also put in the Junk folder. I can't find the rhyme or reason for the choice of the filter. I always install the latest updates on all of my devices. Can someone tell me how to solve this problem? Thanks in advance.

    There are two ways to designate as junk mail. One is based on the local 'training' that you used in the Mail application. These emails are marked in Brown, the other method is by e-mail based service provider on whatever rules or databases they use. These emails end up in the Junk folder, but are not marked in Brown.

    The only way to deal with the second type is to open a session in the portal provider email, change your preferences or update the address book provider.
