Learn how to identify your BookArc version and choose the correct insert for your MacBook model with this simple step-by-step guide.
Quick answer
To pick the right BookArc insert, first confirm your stand is the current version (2015 or later), then match your MacBook model to the corresponding lettered insert (A–H).
Why the insert letter matters
BookArc inserts are lettered (A–H) for the current stand version, while older stands used numbered inserts (1–8). Using the wrong insert can leave your MacBook unstable or not seated properly, so matching the letter to your model is essential.
Each insert adds compatibility for specific MacBook models. For example, Insert I fits the 13-inch MacBook Air (M2/M3) and 15-inch MacBook Air (M2/M3), while Insert F fits the 16-inch MacBook Pro (USB-C) and 13-inch MacBook Air (M1).
Steps to choose and install your BookArc insert
- Identify your BookArc version: Check the inserts that came with your stand. If they are numbered (1–8), you have an older version and these lettered inserts won't fit. If they are lettered (A–H), you have the current version (2015 or later). Only proceed if your stand uses lettered inserts.
- Match your MacBook model to the insert letter: Refer to the compatibility list for each insert letter. For example, Insert I supports the 13-inch and 15-inch MacBook Air (M2/M3), Insert F supports the 16-inch MacBook Pro (USB-C) and 13-inch MacBook Air (M1), and Insert C supports the 12-inch MacBook. Choose the letter that matches your exact model. Double-check your MacBook's year and size; using the wrong letter can cause an unstable fit.
- Install the insert: Remove the current insert from your BookArc by gently pushing it out from the back. Align the new insert with the slot and press it firmly until it clicks into place. Place your MacBook in the stand to verify it sits securely. If the MacBook wobbles or doesn't slide in easily, you may have the wrong insert—recheck the compatibility list.
Available BookArc inserts
- BookArc - Insert I: Insert I adds compatibility for the 13-inch MacBook Air (M2/M3) and 15-inch MacBook Air (M2/M3) to the current BookArc (2015 and later). If you own a recent MacBook Air, this is the insert you need to ensure a secure fit.
BookArc - Insert I - BookArc - Insert F: Insert F adds compatibility for the 16-inch MacBook Pro (USB-C) and 13-inch MacBook Air (M1) to the current BookArc (2015 and later). This insert is ideal for users with a larger Pro or an M1 Air, providing a stable vertical dock.
BookArc - Insert F - BookArc - Insert C: Insert C adds compatibility for the 12-inch MacBook to the current BookArc (2015 and later). If you have the compact 12-inch MacBook, this insert ensures it fits snugly without wobbling.
