Research notes & open questions

Detailed credit rate and storage/egress economics require plan-specific validation. Image beta stability, concurrency entitlement and queue observations are separate from the available resource-class list. Uploaded assessment research (2026-09-21): CI: submitted research reports 9/19 checklist items resolved. Submitted open questions: repository: Which first-party docs confirm PR-event builds and commit/PR status reporting for the Performance plan?; cache: Are parallel-build controls (parallelism/test splitting) documented for macOS resources on the Performance plan?; support_channels: What are the documented support hours and scope for the Performance plan?; sla: Is there a contractual availability SLA with remedy applicable to the Performance plan?; identity: Are MFA and granular scoped roles documented as applicable to the Performance plan?; isolation: What workload-isolation and credential-protection commitments apply to macOS cloud jobs?; data_lifecycle: What are the documented retention, deletion, and backup responsibilities for build data?; security_docs: Where are the accessible contractual data/privacy terms (privacy policy, DPA) for the Performance plan?; cancellation: What are the documented cancellation, renewal, and refund terms for the Performance plan?; operator: Who is the contracting operator and where are the current terms/privacy policies?

Calculation & assumptions

100 × reference price ÷ (reference price + offering price). Same category and chip; 2 providers. Uses an estimated price, not a complete invoice.

100 × USD 1,200 ÷ (USD 1,200 + USD 2,880) = 29/100.

Credit purchase increments and required account charges need normalization.

One user and one concurrent job or machine.
Excludes optional add-ons, transfer, extra storage and applicable taxes.
Estimated from the available listed price; unresolved charges and terms remain in the source details.
Credit spend uses the published conversion and minimum purchase, without adding the same credits twice. Purchase increments may change the invoice.
