MacBook 2015; logo of start-up after connecting.

Tried searching everywhere, but without success.

I stop my Macbook while it was plugged into an external monitor a few days ago. Since then, whenever I try to log in, it accepts my password, shows the photo of profile for a few seconds, then goes to apple boot logo. It remains on the screen until what turned off.

After power turned off, I have to reset the SMC to get it to power back on. The same problem occurs after that.

I'm about to re - install the operating system, but I wanted to check if anyone knows a more simple solution.

Thanks in advance.

Well, problem solved. Started in recovery and ran a repair and that seems to have done the trick.

    After referring upgrade to the macbook pro mid 2011 for OS X 10.11.15, I have to do a lot to restart, as well as the different key combinations in order to get mac (even that becomes difficult to solve the problem now!)

  • How to connect 12 '' MacBook (2015) to a 24 "or 27" Apple Cinema Display AND fresh!

    I made this post on my site here: https://underground.net/how-to-connect-an-apple-display-to-a-usb-c-macbook/ (which I will update regularly)

    This installation took me a LONG time to understand, but it works very well, no wake mode 'sleep', etc.

    To connect the new MacBook to a 24″ Cinema Display or Apple 27″ LED Display Monitor (who both have a record which is the same as the Thunderbolt connector, but are not actually screens Thunderbolt) you can opt for a really cheap option, as the following point 3.1 AllSmartLife USB Type C adapter Mini DisplayPort Amazon for $ 20 :

    That works very well, but you cannot load your computer when you are connected to the screen, nor can you plug something else on your computer as an external hard drive, etc.

    To be able to recharge your computer AND connect to the screen AND connect other devices to your MacBook, you need the following configuration, and it works great, btw.

    1 first download this USB-C for USB multi-port, Belinda® USB-C for 3 ports USB 3.0 , which is about $ 36 on Amazon.

    2 then, you need an expensive element, StarTech.com USB 3.0 to DisplayPort 2560 x 1600 video card Multi monitor external adapter (USB32DPPRO), which is around $74 on Amazon:

    3 Finally you need a cheap item, the Cable questions DisplayPort / Mini DisplayPort male to female adapter at $ 9 on Amazon:

    Plug all the in such things and he ends up you look pretty clean where it connects to the computer, as you can see below and you can plug in the USB port of the screen on the hub and use the speakers on the screen, AND you still an available for a hard drive, external USB 3.0 port.

    It will cost you around $119! Wow, that's a LOT, but it works. Or you can go cheap and just get the first card for $20 but charge your MacBook by disconnecting from time to time to plug in the charger. What a PAIN in the * Apple.

    The new MacBooks coming will be equipped with a combined USB/Thunderbolt-c plug that should * hope * connect a screen and charge at the same time cheaper, but who knows?

    If you want me to your post something, I can put it on the MacBook 2015 using forum boards.

  • Time Capsule A1355 no light, no sound? worked this morning now after connecting it, first go-ahead for colid quickly followed by the longest fixed Orange, which turns off and then nothing? He's dead now?

    Time Capsule A1355 no light, no sound? worked this morning now after connecting it, first green light solid, quickly followed by amber is more solid, which turns off and then nothing? I'm not in the airport or if directly connected to the Macbook air utility. It is running the latest firmware, updated 7 days ago and everything was fine until now. Tried both a soft and a hard reset factory but still nothing, but the same brief glow only after restarting each time before going dark again? Any ideas if it can be fixed or if it's as I read elsewhere dead now?

    Thank you

    Any ideas if it can be fixed or if it's as I read elsewhere dead now?

    He died... the fact that the main witness turns off is unusual in this model.

    It is common to the next... A1409 (gen4)

    What happens in the Gen3 is normally a few deaths on the Board... or a bunch of capacitors is low...

    See s/apple-time-capsule-repair/new-issue-with-a1355-gen-3-tc https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem

    If yours is a very fine introduces Gen3 just before Gen 4, it is possible that the same fix on the Gen 4 could work.

    s/Apple-time-capsule-repair/GEN4-a1409-issues https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem

    I found early Gen4 may fail as Gen3 but must admit that I am yet to see the Gen3 with welding problems.

    I doubt repair is worth it. The Gen3 is now about 6 years... give or take... This is way beyond the standard lifetime of a TC.

    If you want to play, I'm happy to help you... but I would not spend money on it.

    Thanks in advance

    > in the last few weeks my laptop new (6 months) started having problems connecting to wireless devices
    Have you changed some settings or perhaps updated driver WLAN? I mean, I can't imagine that problems start without reason.
    It is not easy to say what may be the problem. Perhaps, you must reinstall the recovery image and test the feature with the factory settings.

  • Unusable slow of the macbook pro at the start of the internal drive

    Hello

    A couple of days my macbook pro (mid 2012 13 inches) has become unusably slow. Nothing doing, even just by clicking on the desktop would give the minutes of spinning beach ball.

    To troubleshoot I tried the following:

    Safe mode: same questions, constant beach ball

    Apple Hardware Test (extended test): no found error.

    Booted in single user mode and drive repaired using fsck: I got the message 'volume (name) seems to be OK. "

    Finally, I started again in mac os x and the console have pulled up to see if I could find something.

    I found an online "localhost kernel [0]: disk0s2: i/o error." at the same time my problems began. Due to this I thought that my drive was dying.

    After installing a new disk and hang the old an external, I decided to start just to see what would become of the former.

    To my dismay, it worked perfectly, smooth as butter and no rotation beach ball.

    So I think that's not the drive that is at fault.

    What else could be the problem and how would approach I find it.

    Thank you

    I have the same problem on my Macbook Pro, which also runs on OS X Yosemite. and is the same model.

    It starts very well I can access my files for about 2 minutes and then it freezes and slows down just. This is for me the wheel of death of Rainbow forever, regardless of how long I left my Macbook on the race. I have nothing to cause this problem, he slowed down just in itself, but I can still access my files

    I tried to search for this problem on the internet, but there is no help for this issue at all or not so much information about it.

    Docking station opens, but Rainbow wheel does not disappear and the freeze continues.

    I tried both SCM and reset the PRAM, but that did nothing.

    Can someone help us? I would like it to go faster still.

    * UPDATE *.
    He seemed to have solved my problem!

    I left my Macbook to run while loading slowly after sign in about 20 minutes. Then all of a sudden the Finder came back and it seems to work fine... for now... give that a try.

  • Satellite A100 PSAA2E Setup hangs after connecting new HARD drive

    Hello

    I have a problem with TOSHIBA Satellite A100 PSAA2E (3 year old laptop)
    I bought the new SAMSUNG SPINPOINT 250 GB SATA (model HM250JI) hard drive.

    After connection, the computer hangs on the first screen. I can't access the BIOS Setup (press F2)
    I can't boot the CD of form (I can't select same drive to start by pressing F12)

    It just hangs.

    When the HARD drive is unplugged I can access the configuration of the BIOS or boot from CD. When the original hard drive (FUJITSU 40BG) is connected, everything is ok.

    I updated the BIOS to version 1.5 to the a more recent 2.6, but it did not help.

    HARD drive runs under windows xp, when connected by USB port. It is formatted with NTFS: a primary partition(15GB), a stretch with two logical partitions (20BG, GB 215).

    You have no idea where could be the problem?
    Should I format hard drive in a different way?

    BR,

    hosss

    Hello

    Check if your new HARD drive has been fitted with a small jumper that controls the master/slave/c-salt settings.

    A friend of mine bought a new HARD drive and BIOS didn't recognize because the rider has been set to the wrong position.

    Good bye

  • Touchpad on my Satellite L50D-B stops working after connecting

    Hello

    I bought L50D-B 12/2014, 2 days ago, it started.
    After I login I have the touchpad work although all commissioning, but once the start finished it stops.

    I use a bluetooth mouse, but have used same mouse since I bought the laptop, the printer, the same wifi connection. Same Antivirus software.

    The only thing I can think of that changed is that I removed Norton trial for backup software remotely.

    Any ideas.

    Thank you :-)

    Hello

    Touch pad can be turned on and off using the FN + F5.
    Have you checked this feature in the past?

    In addition, you can try to uninstall the touchpad driver (Control Panel? programs and features)
    Here, you should see the momentum or Synaptics touchpad driver.

    After you have uninstalled the driver for the touchpad, visit the Toshiba UE driver page, and then download and reinstall the driver from the touchpad still. Reboot the laptop and test if it helped to solve your problem

  • My PC starts immediately after stopping off for a considerable time

    My new PC will not start immediately after the power supply is cut off for several hours. However, it starts up after several minutes of trying. Is this a problem related to the power supply or other materials? I assembled just this new pc, and before that, it never happened. Here are the specs of my pc:

    GX650 Bronze PSU CoolerMaster; Processor Intel i5 2320; Intel DH67CL mobo. 6750 2 GB DDR3 graphics card Sapphire; 2 x 4 GB Corsair RAM; Kingston 64 GB SSD; WD 1 TB HARD drive; ASUS DVDRW
    My PC is connected to the mains through an inverter 600w APC.
    Is it possible that it could also because of the connection of power supply of the pc case itself? For the record, the case is an old one that has experienced a recent surge that destroyed my previous mobo and basically almost everything in it.
