Recentemente eu troquei o SSD de 120GB por um de 480GB.

Já reinstalei o High Sierra nele.

Por favor, me ajude a solucionar este problema.

Agradeço desde já.

Não consigo abrir o arquivo de extensão XLXS no meu Mac Pro 2015. Recebo esta mensagem de erro: O Microsoft Excel encontrou um problema e precisa ser fechado.

O arquivo foi enviado por e-mail.

Como recuperar arquivo do Excel?

Exrcicio d teste. (tentei escrever Exercicio de teste) e ele saltou várias letras como podem ver.

Outras vezes aparece um ee que não teve um duplo click na tecla e.

Este facto ocorre aleatoriamente.

Como se trata já de um equipamento de substituição, queria saber se existiam mais casos iguais ao meu.

Other symptoms includes No audio devices found(cant play sound)

Is there any possible reasons for this? I highly doubt is a software problem.

hey guys an update on my issue, i never went for a fix, the problem went away after i left it to rest for a few days, i believe its an overheat issue. my screen has been working fine for the past few months since reporting this. Not sure it will come back, but this is definitely a faulty hardware, and Apple is not admitting it!

Affected model: 2016 Macbook Pro touch bar

I never went for a fix till now and using the same mac, the problem still comes and go, usually happen when overheating/heavy usage. I brought my macbook for de-dusting the fans and apply new heat paste for my processor in hope that it can reduce overheating issues, replacing the whole display costs too much.

Apple did an update for this issue for the FlexGate issue: 13-inch MacBook Pro Display Backlight Service Program. Sadly it doesn’t cover the T-CON issues.

My Macbook Pro suddenly shut down and is not turning on, no chime, no Apple logo. There was no exposure to water. (However, I had kept a steaming bowl of hot water right next to the laptop.But this was in an open kitchen)

The Pro had less than 10% charge when it suddenly shut down. I charged it for another 10 minutes and tried to switch on, but no luck. I charged it completely till the magsafe indicator turned green, still does not turn on. So assumed that the battery is charging fine. I opened the mac and saw no visible corrosion or moisture(two tiny dots below the battery case are white and haven't turned red)

I have tried the following already.

1. SMC reset - With the magsafe adapter connected, when I do the reset the charge indicator turns green from orange.

2. Disconnected and reconnected the battery connector - still no life.

Its been only a year and three months I bought this in India. Could the logic board die out so soon? How to pinpoint if it is indeed the logic board?

Thanks a lot!

I am currently based in a small town in Germany with no apple genius store around. I will be visiting the store in February. Meanwhile any help would be appreciated.

Thanks!!

I should be able to upgrade the ssd to 256gb without much problem right? But which one would one use? or is it only possible to use another original SSD?

Don't need to be a monster of a ssd, just abit larger to store some more media.

Thanks in advance

Basically, I get no audio from my MacBook Pro Retina 13" Late 2013 A1502 16Gb 2.6GHz - everything else works beautifully as ever with this machine (incl USB & power) apart from the sound.

It has *not* experienced any water damage or drops, but I'm pretty sure this problem started when I plugged in my external power speakers' amp to the headphone jack... just like I did everyday before that, but for some reason this time I didn't get any sound output and the volume feedback was delayed when I tried to turn the volume up/down.

Symptoms:

• Built-in speakers don't make any sounds.
• No sound coming from output jack (headphones or external speakers).
• I see the volume no-access icon (circle with diagonal line through it) when trying to change volume
• checked System Preferences->Sound settings: nothing showing up under the Output or Input tabs (no "Internal Speakers" showing up)
• NO RED LIGHT coming from headphone jack... so it's not the optical speaker switch problem most people seem to have.
• In "system information", when I look in sound hardware... no description for input, output, etc...

I've hunted and hunted all over the internet trying all various suggestions that others have had success with - I've tried all of the following, but still no luck:

I've tried all of the following in the listed order but nothing's changed:

• repeatedly plugging & unplugging different types audio equipment to the headphones port (including apple headphones)
• disk utility and run disk repair (no errors)
• tried PRAM/NVRAM resets (I don't hear the "chime" sound)
• tried logging in via a new user account
• tried deleting ~/Library/Preferences:com.apple.systemsound.plist
• plastic toothpick in the hole
• looking in the hole with microscope & 1.8mm led to illuminate - can't see anything obstructions in the hole
• I downloaded and booted the ASD software EFI and OS diagnostics - no errors
• tried disconnecting battery then rebooting
• an isopropyl alcohol swabbed q-tip cotton swab

I also went to see a Genius at the Apple Store - they did their tests and said "there's only two options:

• replace the logic board as we don't replace individual components, or
• use a USB adapter"

The logic board repair quote was extremely expensive as my warranty is over and the charge probably includes replacing all 16Gb of memory too as it's soldered in; and I said I didn't think that last suggestion was very Apple-like - I'd need to carry around an ugly USB adapter and an external speaker/mic device just to hear sound!

So I'm at a loss and need your help!

Everything else works fine on my computer, so I'm willing to get my multimeter out and start testing hardware but I'm not sure where to start (I/O card / Logic board?).

My logic board # is 820-3476-A

Thanks

A few weeks ago, I decided to replace my macbook’s battery - after 5ish years, the only thing about this laptop (the best laptop ever made) was the battery life drained quickly. I ordered a battery + kit from iFixit, and replaced the battery. I conditioned the battery, but every time it discharged it would jump from above 50% battery to 7% battery, then die shortly after (i.e. a very discontinuous discharge). I received a replacement battery for the replace from iFixit, and replaced again. However, I’m still having the same problem with the battery jumps . I figure it’s unlikely to be the battery, but am unsure what else could could be causing the issue. I’ve reset PRAM and SMC.
