macos – Removing free partition on Macbook Macintosh HD

Let me tell you the story to understand the problem.

I installed Ubuntu 20.04 on my mac as the second OS. Later I decided to delete it, and being not good in all this stuff, I decided to just remove the 30gb partition I gave for Ubuntu. However, EFI partition was left.

I downloaded Paragon and erased this EFI. But it is not merged still with my Macintosh HD!

Paragon - disks structure

So my question is how to merge it (include literally the 314.57 Mb partition) with my hard disk (APFS-container)?

I tried to format it as HFS+ and then tried to make it APSF but my system felt and I had to install macOS again.

P.S. Disk Utility says that there is a trouble and to repair it, I need to go to recovery mode. But when I go to RM, it says the same thing – even though I turned off filevault as some sources say.

I will be very thankful to you for your response!

macbook pro – Where in System Preferences do I find how to enable extensions?

A friend of mine has a Mid 2012 MacBook Air running Catalina, and he’s trying to get the Android emulator BlueStacks running on it. He gets an error saying “System extension blocked. Enable the extension from Security & Privacy System Preferences pane by clicking ‘Allow’ button and BlueStacks will launch again.” I looked in that pane, and couldn’t find anything like that. I’m obviously missing something here but I don’t know what!

A screenshot of the error is attached:

network – Macbook 2007 (A1181) Wi-Fi issues in Windows

I have:

  • Macbook A1181
  • Windows 8.1 in Bootcamp with the latest patches
  • All bootcamp drivers installed
  • Keenetic Viva router with 2.4/5 GHz dual-band Wi-Fi, located in ~1m from the Macbook

The issue is that download/upload speed via Wi-Fi is very low in any app (~60kbps) and often interrupts. On the other hand, ethernet connection works great.

And the same Macbook works great with Wi-Fi when I boot macOS, but, unfortunately, I need Windows.

Other devices, like M1 Macbook Pro (late 2020), iPhones and lots of Android phones (even 2.4 GHz) work fine too, so it seems to be a driver issue.

Any ideas on how to fix it?

macos – Macbook Pro 2016 – Big Sur Battery Issue after replacement

Background – i bought a 2016 Macbook Pro (A1708) a few weeks ago that was at 800+ cycles and the battery was listed as “service recommended”, would not charge past 1% and switch off if unplugged. So i bought a new battery and installed it. Little did i know that there was a replacement program for the 2016/2017 MAcbook Pro’s that had issues after Big Sur upgrade..doh! So now Apple wont touch me as i replaced the battery but the issue still persists even with a new battery. I have attempted an SMC reset and PRAM/NVRAM resets and it still doesn’t work. I have wiped SSD and gone back to Mojave (same issue) then upgraded back to the latest version of Big Sur.

Did this bug with Big Sur brick something on the logicboard/SMC? Has anyone else had this issue and worked out how to resolve?

2020 M1 MacBook Pro: Built-in display does not show entire desktop (truncates 300px from right and 200 px from bottom)

It seems like I have a desktop which is slightly larger than my screen. When I maximise a window the bottom portion (approx 300 pixels) and right portion (approx 200 px) are not visible. I can move the mouse to that invisible and perform click operations but the pointer is not visible on screen. (It is shown when in the visible region). Attempting to scroll beyond the visible extremities does not pan the screen.

See the attached screen shots. For the truncated ones, I captured a portion of the visible regions, starting at the top of the screen and moving to the right-most visible (or bottom most). For the non-truncated ones I moved the mouse enough such that I could be confident of being at the extremity of the desktop – but I had to do this unseen.

Horizontal truncation:

The same thing happens with vertical truncation, but the images take up a lot of vertical space in this post and don’t really add much (though I can add them if this is desired).

I’ve had to move the Dock to the left of the screen in order to make it visible but I would prefer to keep it on the bottom.

In terms of my machine setup:

I’m using a new 2020 issued M1 MacBook Pro running Big Sur. I’ve tried both with and without an external display. With an external display, that external display shows fine (and has no truncated region). But in both setups, the built-in display of the laptop is truncated.

In case it matters: I migrated my data to it from a 2015 edition MacBook Pro which had been upgraded to Mojave.

I’ve tried looking in System Preferences but don’t see anything related to screen size in the Displays subsection. I’ve also tried looking for zoom/magnifying settings (such as might be used for a11y reasons), again to no avail.

I’d welcome suggestions for things to try here.

display – Lag on external monitor using a Macbook Air 2017 with a Intel HD Graphics 6000 1536 MB and running macOs Big Sur 11.2.3: what could be the solution?

HOST MACHINE: Macbook Air 2017

GRAPHICS: Intel HD Graphics 6000 1536 MB

Bus: Built-In

VRAM (Dynamic, Max): 1536 MB

Vendor: Intel

Device ID: 0x1626

Revision ID: 0x0009

Metal Family: Supported, Metal GPUFamily macOS 1


Resolution: 1920×1080 (1080p FHD – Full High Definition)

UI Looks like: 1920 x 1080 @ 60.00Hz

Framebuffer Depth: 30-Bit Colour (ARGB2101010)

Display Serial Number: H9XZ103518

Main Display: Yes

Mirror: Off

Rotation: Supported

Automatically Adjust Brightness: Yes

Connection Type: Analog VGA or Analog Over DVI-I

Adapter Firmware Version: 0,00

1) At home I use my mac connected to a SAMSUNG 2494HS via VGA + CableDeccon video adapter.
The default resolution is 1920×1080 at ~60HZ.

Recently ( maybe correlated to the new macOs update) I noticed some lag in the external monitor. The events occured only when I run VirtualBox (v. 6.1) and I increase the resolution: above a certain threshold the VM starts to lag.

It is not correlated to any specific VM, but is the same with any.

2) If I use the HDMI cable (whatever type) or I set ad unscaled resolution with VGA, the display looks blurry.

3) Last but not least, if I close the mac and use only the external display with the setting as 1) the VM does not lag any more.

What could be the problem and possible solutions?

I tried to unscale the resolution, use differents setting for the VM (different video adapter, memory size, processors…) but with no success.

MacBook charging extremely slowly, after using 3rd party USB-C charger

I have a 16″ 2019 MacBook Pro.

A few days ago, I didn’t have my MacBook charger on hand. After a quick internet research of whether or not it works, I borrowed my wife’s DELL XPS charger (USB-C, 130W I believe). My MacBook charged fine with it.

A few days later, I noticed that my MacBook is charging very slowly (with my Apple 96W charger). I reset the SMC, rebooted, tried a different wall outlet, installed all system upgrades. No luck. Charge speed is around 1% point every 20 minutes with all apps closed. When I run a computing intense task (having a lot of Google Chrome tabs open, or compiling code), the battery discharges.

I checked the battery status with coconutBattery, but things seem to look normal. The only thing that seems off is that charging wattage. I’d expect that to be somewhat close to my 96 watt maximum.

See the attached screen shot. Note that this is with all apps closed.

Are my issues due to my charger experiment a few days ago? Is this just coincidence and my Apple charger went bad?


Can I drive this 34 inch samsung display with my macbook pro?

I own a 13 inch early 2015 macbook pro and am in the market for an ultrawide display for my home office. I’ve landed on this display as a contender for purchase, but am worried that my macbook will not be able to drive the display properly.

The resolution for the display is 3,440 x 1,440. According to apple here, the HDMI port can support resolutions up to 3840-by-2160 at 30Hz. What about the thunderbolt 2 port? I understand the thunderbolt 2 port also doubles as a minidisplay port, however apple does not mention supported resolutions.

Can I use the minidisplay port to drive this monitor? If not, is my only option the HDMI? Could I do thunderbolt 2 to thunderbolt 3?

Any information on how I might be able to drive this display would be appreciated.
