High impedance headphones on MacBook Pro 2021

Good news for audiophiles out there. Apple’s new M1 Pro and M1 Pro Max MacBook Pros feature an adaptive voltage headphone amplifier, meaning it optimizes itself to the headphones you’re using. With these two models, gone is the concern whether 80 ohm or 250 ohm headphones will work.

“When you connect headphones with an impedance of less than 150 ohms, the headphone jack provides up to 1.25 volts RMS. For headphones with an impedance of 150 to 1k ohms, the headphone jack delivers 3 volts RMS. This may remove the need for an external headphone amplifier.”

So, if you love Beyerdynamic’s DT 990 Pro 250 ohm Open-back Studio Headphones, you can rest assured that your new MacBook Pro will power them with aplomb.

 

Add MySQL to terminal shell in Mac OS X

Mac OS X 10.6 snow leopard uses the bash shell by default. If you install MySQL from the disk image (dmg) from http://dev.mysql.com/downloads/, you can make it easy to access the mysql binary from the command line by adding it to your bash path.

Here’s how:

Open terminal, and type:

echo 'export PATH=/usr/local/mysql/bin:$PATH' >> ~/.bash_profile

This adds the default location of the MySQL binary to your shell environment.

Then, you need to force the system to reload your .bash_profile file. Again, from terminal, enter:

. ~/.bash_profile

You can check your environment variables by typing in terminal:

env

Now, to access MySQL from the command line, you only need enter:

mysql

Google flagging all search results as “harmful”

Searching for GarageBand ’09 topics this morning, I noticed a pattern — one that’s virtually impossible to notice given Google’s new self-appointed role of protector of digital humanity.

Every link is flagged as “This site may harm your computer” — even trusted pages on the topic, such as pages on Apple.com. Any attempt to visit the resulting links are intercepted by Google, in effect preventing me from visiting the site. Sounds like a good idea, except it isn’t, because Google can’t seem to get it right, and Google isn’t interested in fixing sites that are incorrectly flagged.

Apple’s Teams Wiki Server supports very few HTML tags out of the box, in order to keep things simple.

Here’s how: Continue reading →

Apple: Drop the Smug Ads

I’m sick of Apple’s snobbery. As an AAPL stockholder and customer, I’m fed up with Apple alienating and insulting PC users.

Now, I’m not a Mac-hater; far from it. In fact, I’m a recent re-convert, having come back to the Mac platform after leaving it for Windows 95 when Microsoft was turning itself around based on Bill Gates’ long-overdue realization that the web was the future. Now, I’m primarily a Mac user. Up until just over a year ago, I was primarily a Windows user. Continue reading →
