This is a iMac icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,300 icons, all in the same style and quality.
This logo is a computer monitor. There is a rounded rectangle longer horizontally than vertically, with a line in the lower quarter of the rectangle. In this lower quarter, there is a single centered dot. Protruding from the center of the bottom is a base that is shaped like a bell.
