While waiting for macOS Universal Control, I wanted to try AirPlay Receiver. Unfortunately, it is not supported (“locked”) on my older macBook. But recently I stumbled upon Mr. Macintosh’s “Airplay BLOCKED on Monterey? How to unlock it!” video on YouTube!
I suddenly experienced a strange issue today - the row of number keys on my 1stPlayer DK 5.0 Lite mechanical keyboard, i.e. the keys from
9, would output the wrong number! Specifically, hitting all numeric keys in order would output
1678923450 instead of
1234567890. This happened while gaming and I have no idea what caused it.
I found that Oracle VM VirtualBox 6.1 was running very slowly on my brand new Windows 10 PC.
Initially I thought it was to do with VirtualBox, e.g. insufficient cores or memory, the display controller (VBoxSVGA), insufficient video memory, etc. And then I thought it might be an AMD thing, so had a look at BIOS, e.g. nested AMD-V, etc.
I recently installed Ubuntu 20.04 LTS (Focal Fossa) (dated 23 April 2020), with the intention of creating a VM using VirtualBox 6.0.22 (released 15 May 2020). I had issues with VirtualBox guest additions, and this is how I solved it.
On my MacBook Pro with retina display, when I take a screenshot, the image is saved with a DPI of 144. But, using ImageOptim to compress the image with Strip JPEG/PNG Metadata enabled will remove (or reset) the DPI setting to 72 DPI - resulting in a double sized image when displayed in Preview and Quick Look. Here is how I correct this.
Grrr, to no one’s surprise, my MacBook Pro with butterfly keyboard is experiencing keyboard issues. In my case, a keypress on “j” is often triggered twice, resulting in “jj”. And with the lockdowns, I don’t want to risk a repair! So, here is a quick workaround using Karabiner-Elements v12.9.0.
While testing out Grav, it’s quite easy to setup a local instance on a macOS computer, since macOS already comes with a suitable web server (Apache 2.4.x and PHP 7.x). I never realized I didn’t actually describe how I set it up, but just wanted to point out one important change.
I just spent hours trying to figure out and fix a Windows 10 machine that was taking 100% disk, 100% RAM and about 50% CPU with absolutely nothing running. Of course, I initially blamed the user... then, a misbehaving (hidden, background) app... then, malware / virus... the, a runaway Windows Defender... then, a hard disk / hardware failure... but ultimately discovering the culprit is - drum roll - Microsoft Windows itself! As usual!
Today I tried to copy files and folders off a USB hard disk (NTFS formatted) on my Windows 7 desktop. I encountered multiple files with permission problems. The manual method to change permissions is very tedious, so I created a script (DOS batch file) to do the same.
I got macOS Mojave 10.14 / 10.14.1 installed in Parallels very easily! But encountered some graphics issues with certain apps... and managed to find a workaround.
On my hosting provider, there is a slight tweak needed to get Grav to run on PHP 5.6. Here's the solution:
I've been experiencing this problem for a while - when presenting using Microsoft PowerPoint for Mac 2016 (version 15) on an external monitor (or LCD projector), PowerPoint used to both the presentation slide show and the Presenter View on my notebook display, instead of Presenter View on the notebook and the full-screen slide show on the external monitor. Recently, I found the solution!
I upgraded my iPad to iOS 11.0.0 last night - and this morning realized that my IBM Verse contacts had disappeared from my iPhone! I didn't update my iPhone, nor did I make any changes of significance lately. Most upsetting! Here's a guide to restoring your contacts.
Microsoft PowerPoint 2016 for Mac (aka version 15) has a strange quirk - when I copy and paste images from Preview or most other applications, the image gets copied in Tagged Image File Format (TIFF). The image is practically uncompressed (or possibly minimally compressed), resulting in very, very huge PPTX files! Plus: Removing unwanted font references.
So I got a new MacBook for work and I didn't realize upon next reboot, the enterprise profile had mandated FileVault encrypt the start up disk, and Apple had recommended an upgrade to macOS Sierra at the same time! You can imagine triggering both simultaneously upon reboot didn't go well at all!
Apple has noted that a number of users may experience an issue with iCloud setting being enabled after upgrading to iOS 10.3. For me, I had quite the opposite experience, as iOS 10.3 finally enabled some iCloud applications that I had never gotten working for a long time!
Recently I realized that the latest macOS Sierra 10.12 upgrade also updated Apache and PHP to newer revisions (2.4.23 and 5.6.24 respectively), but reverted to the default configurations. My previous post on Enabling Apache and PHP on OS X 10.11 needed a slight change too.
