This page has the assets for current MacTech Pro logos and banners in a variety of sizes.
There are two types of logos — with outline/halo and without. The first one in each row is the “without” version. The second one is the “with” outline version (which is why it appears to be slightly smaller when displayed on a white background. Note: black background is not part of graphic — it’s only shown to show the halo.)
Here are the different sizes.
